Lets's calculate LCM of 99,353,257
Given numbers has no common factors except 1. So, there LCM is their product i.e 8981379
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8981379
Therefore, the GCF of Fractions 65/99,99/353,979/257 is 1/8981379
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 99,353,257 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,353,257) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(99,353,257) x common factors =1 x 1 = 1
LCM(99,353,257) = ( 99 × 353 × 257 ) / 1
LCM(99,353,257) = 8981379 / 1
LCM(99,353,257) = 8981379
