Lets's calculate LCM of 846,1542
2 | 846, 1542 |
3 | 423, 771 |
141, 257 |
∴ So the LCM of the given numbers is 2 x 3 x 141 x 257 = 217422
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/217422
Therefore, the GCF of Fractions 782/846,2490/1542 is 2/217422
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 846,1542 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(846,1542) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(846,1542) x common factors =6 x 1 = 6
LCM(846,1542) = ( 846 × 1542 ) / 6
LCM(846,1542) = 1304532 / 6
LCM(846,1542) = 217422
