So the greatest common factor 643,757,356 is 1.
Lets's calculate LCM of 383,103,860
Given numbers has no common factors except 1. So, there LCM is their product i.e 33926140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33926140
Therefore, the GCF of Fractions 643/383,757/103,356/860 is 1/33926140
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 383,103,860 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(383,103,860) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(383,103,860) x common factors =1 x 1 = 1
LCM(383,103,860) = ( 383 × 103 × 860 ) / 1
LCM(383,103,860) = 33926140 / 1
LCM(383,103,860) = 33926140
