Greatest Common Factor
We found the factors 69,373,644 . The biggest common factor number is the GCF number.
So the greatest common factor 69,373,644 is 1.
Lets's calculate LCM of 76,89,685
Given numbers has no common factors except 1. So, there LCM is their product i.e 4633340
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4633340
Therefore, the GCF of Fractions 69/76,373/89,644/685 is 1/4633340
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 76,89,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,89,685) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(76,89,685) x common factors =1 x 1 = 1
LCM(76,89,685) = ( 76 × 89 × 685 ) / 1
LCM(76,89,685) = 4633340 / 1
LCM(76,89,685) = 4633340
