Lets's calculate LCM of 21,74,29,835
Given numbers has no common factors except 1. So, there LCM is their product i.e 37630110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/37630110
Therefore, the GCF of Fractions 7/21,3/74,7/29,58/835 is 1/37630110
Least Common Multiple of 21,74,29,835 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 21,74,29,835 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,74,29,835) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(21,74,29,835) x common factors =1 x 1 = 1
LCM(21,74,29,835) = ( 21 × 74 × 29 × 835 ) / 1
LCM(21,74,29,835) = 37630110 / 1
LCM(21,74,29,835) = 37630110
