So the greatest common factor 162,980 is 2.
Lets's calculate LCM of 238,357
7 | 238, 357 |
17 | 34, 51 |
2, 3 |
∴ So the LCM of the given numbers is 7 x 17 x 2 x 3 = 714
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/714
Therefore, the GCF of Fractions 162/238,980/357 is 2/714
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 238,357 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(238,357) = 119
common factors(in case of two or more numbers have common factors) = 1
GCF(238,357) x common factors =119 x 1 = 119
LCM(238,357) = ( 238 × 357 ) / 119
LCM(238,357) = 84966 / 119
LCM(238,357) = 714
