WebThe GCF of 24 and 60 is 12. To calculate the greatest common factor (GCF) of 24 and 60, we need to factor each number (factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24; factors of 60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60) and choose the greatest factor that exactly divides both 24 and 60, i.e., 12. WebOur free online calculator finds the greatest common factor of up to 15 numbers! And shows the work by using the prime factor method.
WebThe first step to find the gcf of 40 and 70 is to list the factors of each number. The factors of 40 are 1, 2, 4, 5, 8, 10, 20 and 40. The factors of 70 are 1, 2, 5, 7, 10, 14, 35 and 70. WebOct 19, 2024 · In our case, 8 satisfies both of these: 8 = 2 ⋅ 2 ⋅ 2. In fact, 8 only has one unique factor! If there is to be a common factor (other than 1) it must be 2. We now need to check that both 18 and 70 have 2 as a factor: 18 = 2 ⋅ 9. 70 = 2 ⋅ 35. Therefore, 2 is the GCF of 8, 18 and 70. Answer link.
WebIn mathematics, the greatest common factor (GCF), also known as the greatest common divisor, of two (or more) non-zero integers a and b, is the largest positive integer by which both integers can be divided.
