Greatest Common Factor
We found the factors 138,964,275 . The biggest common factor number is the GCF number.
So the greatest common factor 138,964,275 is 1.
Lets's calculate LCM of 79,81,570
3 | 79, 81, 570 |
79, 27, 190 |
∴ So the LCM of the given numbers is 3 x 79 x 27 x 190 = 1215810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1215810
Therefore, the GCF of Fractions 138/79,964/81,275/570 is 1/1215810
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 79,81,570 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,81,570) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(79,81,570) x common factors =1 x 3 = 3
LCM(79,81,570) = ( 79 × 81 × 570 ) / 3
LCM(79,81,570) = 3647430 / 3
LCM(79,81,570) = 1215810
