So the greatest common factor 276,280 is 4.
Lets's calculate LCM of 145,136
Given numbers has no common factors except 1. So, there LCM is their product i.e 19720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/19720
Therefore, the GCF of Fractions 276/145,280/136 is 4/19720
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 145,136 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(145,136) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(145,136) x common factors =1 x 1 = 1
LCM(145,136) = ( 145 × 136 ) / 1
LCM(145,136) = 19720 / 1
LCM(145,136) = 19720
