So the greatest common factor 99,75,927 is 3.
Lets's calculate LCM of 138,252,715
2 | 138, 252, 715 |
3 | 69, 126, 715 |
23, 42, 715 |
∴ So the LCM of the given numbers is 2 x 3 x 23 x 42 x 715 = 4144140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/4144140
Therefore, the GCF of Fractions 99/138,75/252,927/715 is 3/4144140
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 138,252,715 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(138,252,715) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(138,252,715) x common factors =1 x 6 = 6
LCM(138,252,715) = ( 138 × 252 × 715 ) / 6
LCM(138,252,715) = 24864840 / 6
LCM(138,252,715) = 4144140
