Lets's calculate LCM of 880,955
5 | 880, 955 |
176, 191 |
∴ So the LCM of the given numbers is 5 x 176 x 191 = 168080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/168080
Therefore, the GCF of Fractions 1242/880,6330/955 is 6/168080
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 880,955 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(880,955) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(880,955) x common factors =5 x 1 = 5
LCM(880,955) = ( 880 × 955 ) / 5
LCM(880,955) = 840400 / 5
LCM(880,955) = 168080
