So the greatest common factor 429,820 is 1.
Lets's calculate LCM of 137,383
Given numbers has no common factors except 1. So, there LCM is their product i.e 52471
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/52471
Therefore, the GCF of Fractions 429/137,820/383 is 1/52471
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 137,383 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(137,383) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(137,383) x common factors =1 x 1 = 1
LCM(137,383) = ( 137 × 383 ) / 1
LCM(137,383) = 52471 / 1
LCM(137,383) = 52471
