So the greatest common factor 709,978 is 1.
Lets's calculate LCM of 432,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 285552
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/285552
Therefore, the GCF of Fractions 709/432,978/661 is 1/285552
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 432,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(432,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(432,661) x common factors =1 x 1 = 1
LCM(432,661) = ( 432 × 661 ) / 1
LCM(432,661) = 285552 / 1
LCM(432,661) = 285552
