Lets's calculate LCM of 1680,8152
2 | 1680, 8152 |
2 | 840, 4076 |
2 | 420, 2038 |
210, 1019 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 210 x 1019 = 1711920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/1711920
Therefore, the GCF of Fractions 712/1680,128/8152 is 8/1711920
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 1680,8152 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1680,8152) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(1680,8152) x common factors =8 x 1 = 8
LCM(1680,8152) = ( 1680 × 8152 ) / 8
LCM(1680,8152) = 13695360 / 8
LCM(1680,8152) = 1711920
