Now, list down the factors of 77
:1,7,11,77
Now, list down the factors of 611
:1,13,47,611
Now, list down the factors of 100
:1,2,4,5,10,20,25,50,100
Greatest Common Factor
We found the factors 77,611,100 . The biggest common factor number is the GCF number.
So the greatest common factor 77,611,100 is 1.
Lets's calculate LCM of 53,17,581
Given numbers has no common factors except 1. So, there LCM is their product i.e 523481
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/523481
Therefore, the GCF of Fractions 77/53,611/17,100/581 is 1/523481
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 53,17,581 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(53,17,581) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(53,17,581) x common factors =1 x 1 = 1
LCM(53,17,581) = ( 53 × 17 × 581 ) / 1
LCM(53,17,581) = 523481 / 1
LCM(53,17,581) = 523481
