So the greatest common factor 77,268,640 is 1.
Lets's calculate LCM of 37,72,457
Given numbers has no common factors except 1. So, there LCM is their product i.e 1217448
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1217448
Therefore, the GCF of Fractions 77/37,268/72,640/457 is 1/1217448
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 37,72,457 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(37,72,457) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(37,72,457) x common factors =1 x 1 = 1
LCM(37,72,457) = ( 37 × 72 × 457 ) / 1
LCM(37,72,457) = 1217448 / 1
LCM(37,72,457) = 1217448
