Since 4 and 5 are coprime, GCF(4, 12, 10, 5) = GCF(4,5) = 1
The GCF of 5 and 10 is 5. The GCF of 4 and 12 is 4.
The GCF of 12 and 20 is 4.
4 (4*3=12, 4*5=20)
The way to get equivalent fractions is to multiply the numerator and the denominator by the same number. 4 x 3 = 12 5 x 3 = 15 4/5 = 12/15 In reverse... The way to reduce fractions is to find the GCF of the numerator and denominator and divide them by it. The GCF of 12 and 15 is 3. 12/3 = 4 15/3 = 5 The GCF of 4 and 5 is 1. That's how you know 4/5 is in its simplest form.
The GCF is 4.
The GCF is 4.
The GCF is 4.
The GCF is 4.
The GCF of 5 and 12 is 1. Factors of 5 are 1 and 5 Factors of 12 are 1, 2, 3, 4, 6, and 12 So the GCF is 1.
It would be 12. After you divided the three numbers by 12, you get 48/12 = 4 ; 60/12 = 5 ; 84/12 = 7. And they cannot be further divided except by 1. Thus, 12 would be the GCF.
The GCF is 4.
