Lets's calculate LCM of 619,751
Given numbers has no common factors except 1. So, there LCM is their product i.e 464869
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/464869
Therefore, the GCF of Fractions 289/619,356/751 is 1/464869
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 619,751 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(619,751) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(619,751) x common factors =1 x 1 = 1
LCM(619,751) = ( 619 × 751 ) / 1
LCM(619,751) = 464869 / 1
LCM(619,751) = 464869
