Lets's calculate LCM of 70,143
Given numbers has no common factors except 1. So, there LCM is their product i.e 10010
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/10010
Therefore, the GCF of Fractions 140/70,154/143 is 14/10010
Least Common Multiple of 70,143 with GCF Formula
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 70,143 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,143) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(70,143) x common factors =1 x 1 = 1
LCM(70,143) = ( 70 × 143 ) / 1
LCM(70,143) = 10010 / 1
LCM(70,143) = 10010
