Greatest Common Factor of 0 Greatest common factor (GCF) of 18 and 48 is 6. We will now calculate the prime factors of 18 and 48, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 18 and 48. Factorize of the above numbers : It is therefore not the greatest common factor. For example, for the set of numbers 18, 30 and 42 the GCF = 6. Factorize of the above numbers : 12 = 2 2 • 3 18 = 2 • 3 2 20 = 2 2 • 5 Build a prime factors table Since 18 is a factor of 90, it is automatically the GCF. We hope it will be very helpful for you and it will help you to understand the solving process. Greatest Common Factor (GCF) of 18 and 13 Below you can find the full step by step solution for you problem. Since 18 is a factor of 90 and it is the largest factor of itself, the greatest common factor of 18 and 90 is 18.

Example 1: 6 is the greatest common factor of 12 and 18. Highest common factor (HCF) Greatest common divisor (GCD) What is the Greatest Common Factor? The GCF is the largest common positive integer that divides all the numbers (12, 18) without a remainder.

It is not difficult to see that the 'Greatest Common Factor' or 'Divisor' for 12 and 18 is 6. We hope it will be very helpful for you and it will help you to understand the solving process. It is therefore not the GREATEST common factor. The greatest COMMON factor depends upon the other number(s) with which 12 has factors in COMMON. The factors of 12 (all the whole numbers that can divide the number without a remainder) are 1, 2, 3, 4, 6 and 12; The factors of 18 are 1, 2, 3, 6, 9 and 18. Example 4: 8 is NOT a factor of 12 or 18.

GCF(12,18,20) Greatest Common Factor is : 2 Calculate Greatest Common Factor for : 12, 18 and 20. Example 2: 2 is a common factor of 12 and 18, but it is NOT the GREATEST common factor. GCF(18,48) = 6. GCF(12,18,30) Greatest Common Factor is : 6 Calculate Greatest Common Factor for : 12, 18 and 30. Greatest Common Factor (GCF) of 12 and 18 Below you can find the full step by step solution for you problem. Example 3: 4 is NOT a COMMON factor of 12 and 18. The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. The second step is to analyze which are the common divisors.
