:1,2,7,11,14,22,77,154
Now, list down the factors of 653
:1,653
Greatest Common Factor
We found the factors 154,653 . The biggest common factor number is the GCF number.
So the greatest common factor 154,653 is 1.
Lets's calculate LCM of 781,153
Given numbers has no common factors except 1. So, there LCM is their product i.e 119493
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/119493
Therefore, the GCF of Fractions 154/781,653/153 is 1/119493
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 781,153 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(781,153) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(781,153) x common factors =1 x 1 = 1
LCM(781,153) = ( 781 × 153 ) / 1
LCM(781,153) = 119493 / 1
LCM(781,153) = 119493
