Lets's calculate LCM of 653,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 647123
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/647123
Therefore, the GCF of Fractions 251/653,378/991 is 1/647123
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 653,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(653,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(653,991) x common factors =1 x 1 = 1
LCM(653,991) = ( 653 × 991 ) / 1
LCM(653,991) = 647123 / 1
LCM(653,991) = 647123
