Lets's calculate LCM of 971,438
Given numbers has no common factors except 1. So, there LCM is their product i.e 425298
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/425298
Therefore, the GCF of Fractions 666/971,779/438 is 1/425298
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 971,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(971,438) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(971,438) x common factors =1 x 1 = 1
LCM(971,438) = ( 971 × 438 ) / 1
LCM(971,438) = 425298 / 1
LCM(971,438) = 425298
