Lets's calculate LCM of 698,155
Given numbers has no common factors except 1. So, there LCM is their product i.e 108190
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/108190
Therefore, the GCF of Fractions 9780/698,9615/155 is 15/108190
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 698,155 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(698,155) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(698,155) x common factors =1 x 1 = 1
LCM(698,155) = ( 698 × 155 ) / 1
LCM(698,155) = 108190 / 1
LCM(698,155) = 108190
