Greatest Common Factor
We found the factors 76,156,418 . The biggest common factor number is the GCF number.
So the greatest common factor 76,156,418 is 2.
Lets's calculate LCM of 19,91,391
Given numbers has no common factors except 1. So, there LCM is their product i.e 676039
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/676039
Therefore, the GCF of Fractions 76/19,156/91,418/391 is 2/676039
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 19,91,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,91,391) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,91,391) x common factors =1 x 1 = 1
LCM(19,91,391) = ( 19 × 91 × 391 ) / 1
LCM(19,91,391) = 676039 / 1
LCM(19,91,391) = 676039
