Now, list down the factors of 856
:1,2,4,8,107,214,428,856
Now, list down the factors of 505
:1,5,101,505
Greatest Common Factor
We found the factors 856,505 . The biggest common factor number is the GCF number.
So the greatest common factor 856,505 is 1.
Lets's calculate LCM of 611,680
Given numbers has no common factors except 1. So, there LCM is their product i.e 415480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/415480
Therefore, the GCF of Fractions 856/611,505/680 is 1/415480
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 611,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(611,680) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(611,680) x common factors =1 x 1 = 1
LCM(611,680) = ( 611 × 680 ) / 1
LCM(611,680) = 415480 / 1
LCM(611,680) = 415480
