Greatest Common Factor
We found the factors 87,147,490 . The biggest common factor number is the GCF number.
So the greatest common factor 87,147,490 is 1.
Lets's calculate LCM of 35,51,521
Given numbers has no common factors except 1. So, there LCM is their product i.e 929985
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/929985
Therefore, the GCF of Fractions 87/35,147/51,490/521 is 1/929985
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 35,51,521 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(35,51,521) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(35,51,521) x common factors =1 x 1 = 1
LCM(35,51,521) = ( 35 × 51 × 521 ) / 1
LCM(35,51,521) = 929985 / 1
LCM(35,51,521) = 929985
