Lets's calculate LCM of 645,362
Given numbers has no common factors except 1. So, there LCM is their product i.e 233490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/233490
Therefore, the GCF of Fractions 817/645,345/362 is 1/233490
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 645,362 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,362) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(645,362) x common factors =1 x 1 = 1
LCM(645,362) = ( 645 × 362 ) / 1
LCM(645,362) = 233490 / 1
LCM(645,362) = 233490
