Greatest Common Factor
We found the factors 816,620 . The biggest common factor number is the GCF number.
So the greatest common factor 816,620 is 4.
Lets's calculate LCM of 87,637
Given numbers has no common factors except 1. So, there LCM is their product i.e 55419
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/55419
Therefore, the GCF of Fractions 816/87,620/637 is 4/55419
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 87,637 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,637) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(87,637) x common factors =1 x 1 = 1
LCM(87,637) = ( 87 × 637 ) / 1
LCM(87,637) = 55419 / 1
LCM(87,637) = 55419
