Greatest Common Factor
We found the factors 102,455 . The biggest common factor number is the GCF number.
So the greatest common factor 102,455 is 1.
Lets's calculate LCM of 715,980
5 | 715, 980 |
143, 196 |
∴ So the LCM of the given numbers is 5 x 143 x 196 = 140140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/140140
Therefore, the GCF of Fractions 102/715,455/980 is 1/140140
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 715,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(715,980) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(715,980) x common factors =5 x 1 = 5
LCM(715,980) = ( 715 × 980 ) / 5
LCM(715,980) = 700700 / 5
LCM(715,980) = 140140
