So the greatest common factor 64,21,912 is 1.
Lets's calculate LCM of 901,506,639
Given numbers has no common factors except 1. So, there LCM is their product i.e 291323934
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/291323934
Therefore, the GCF of Fractions 64/901,21/506,912/639 is 1/291323934
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 901,506,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(901,506,639) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(901,506,639) x common factors =1 x 1 = 1
LCM(901,506,639) = ( 901 × 506 × 639 ) / 1
LCM(901,506,639) = 291323934 / 1
LCM(901,506,639) = 291323934
