:1,3,5,15,41,123,205,615
Greatest Common Factor
We found the factors 61,62,615 . The biggest common factor number is the GCF number.
So the greatest common factor 61,62,615 is 1.
Lets's calculate LCM of 615,370,431
5 | 615, 370, 431 |
123, 74, 431 |
∴ So the LCM of the given numbers is 5 x 123 x 74 x 431 = 19614810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19614810
Therefore, the GCF of Fractions 61/615,62/370,615/431 is 1/19614810
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 615,370,431 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(615,370,431) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(615,370,431) x common factors =1 x 5 = 5
LCM(615,370,431) = ( 615 × 370 × 431 ) / 5
LCM(615,370,431) = 98074050 / 5
LCM(615,370,431) = 19614810
