:1,19,29,551
Now, list down the factors of 643
:1,643
Greatest Common Factor
We found the factors 551,643 . The biggest common factor number is the GCF number.
So the greatest common factor 551,643 is 1.
Lets's calculate LCM of 189,769
Given numbers has no common factors except 1. So, there LCM is their product i.e 145341
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/145341
Therefore, the GCF of Fractions 551/189,643/769 is 1/145341
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 189,769 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(189,769) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(189,769) x common factors =1 x 1 = 1
LCM(189,769) = ( 189 × 769 ) / 1
LCM(189,769) = 145341 / 1
LCM(189,769) = 145341
