Greatest Common Factor
We found the factors 87,461,653 . The biggest common factor number is the GCF number.
So the greatest common factor 87,461,653 is 1.
Lets's calculate LCM of 91,20,689
13 | 91, 20, 689 |
7, 20, 53 |
∴ So the LCM of the given numbers is 13 x 7 x 20 x 53 = 96460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/96460
Therefore, the GCF of Fractions 87/91,461/20,653/689 is 1/96460
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 91,20,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,20,689) = 1
common factors(in case of two or more numbers have common factors) = 13
GCF(91,20,689) x common factors =1 x 13 = 13
LCM(91,20,689) = ( 91 × 20 × 689 ) / 13
LCM(91,20,689) = 1253980 / 13
LCM(91,20,689) = 96460
