Lets's calculate LCM of 238,529,980
2 | 238, 529, 980 |
7 | 119, 529, 490 |
17, 529, 70 |
∴ So the LCM of the given numbers is 2 x 7 x 17 x 529 x 70 = 8813140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8813140
Therefore, the GCF of Fractions 77/238,38/529,699/980 is 1/8813140
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 238,529,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(238,529,980) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(238,529,980) x common factors =1 x 14 = 14
LCM(238,529,980) = ( 238 × 529 × 980 ) / 14
LCM(238,529,980) = 123383960 / 14
LCM(238,529,980) = 8813140
