:1,3,229,687
Now, list down the factors of 959
:1,7,137,959
Greatest Common Factor
We found the factors 687,959 . The biggest common factor number is the GCF number.
So the greatest common factor 687,959 is 1.
Lets's calculate LCM of 411,139
Given numbers has no common factors except 1. So, there LCM is their product i.e 57129
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/57129
Therefore, the GCF of Fractions 687/411,959/139 is 1/57129
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 411,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(411,139) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(411,139) x common factors =1 x 1 = 1
LCM(411,139) = ( 411 × 139 ) / 1
LCM(411,139) = 57129 / 1
LCM(411,139) = 57129
