Greatest Common Factor
We found the factors 1218,1789 . The biggest common factor number is the GCF number.
So the greatest common factor 1218,1789 is 1.
Lets's calculate LCM of 983,7290
Given numbers has no common factors except 1. So, there LCM is their product i.e 7166070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7166070
Therefore, the GCF of Fractions 1218/983,1789/7290 is 1/7166070
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 983,7290 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(983,7290) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(983,7290) x common factors =1 x 1 = 1
LCM(983,7290) = ( 983 × 7290 ) / 1
LCM(983,7290) = 7166070 / 1
LCM(983,7290) = 7166070
