We found the factors 75,725,420 . The biggest common factor number is the GCF number.
So the greatest common factor 75,725,420 is 5.
Lets's calculate LCM of 81,52,142
2 | 81, 52, 142 |
81, 26, 71 |
∴ So the LCM of the given numbers is 2 x 81 x 26 x 71 = 299052
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/299052
Therefore, the GCF of Fractions 75/81,725/52,420/142 is 5/299052
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 81,52,142 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,52,142) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(81,52,142) x common factors =1 x 2 = 2
LCM(81,52,142) = ( 81 × 52 × 142 ) / 2
LCM(81,52,142) = 598104 / 2
LCM(81,52,142) = 299052
