So the greatest common factor 121,640 is 1.
Lets's calculate LCM of 413,356
Given numbers has no common factors except 1. So, there LCM is their product i.e 147028
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/147028
Therefore, the GCF of Fractions 121/413,640/356 is 1/147028
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 413,356 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(413,356) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(413,356) x common factors =1 x 1 = 1
LCM(413,356) = ( 413 × 356 ) / 1
LCM(413,356) = 147028 / 1
LCM(413,356) = 147028
