Greatest Common Factor
We found the factors 53,56,755 . The biggest common factor number is the GCF number.
So the greatest common factor 53,56,755 is 1.
Lets's calculate LCM of 689,401,613
Given numbers has no common factors except 1. So, there LCM is their product i.e 169365157
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/169365157
Therefore, the GCF of Fractions 53/689,56/401,755/613 is 1/169365157
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 689,401,613 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(689,401,613) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(689,401,613) x common factors =1 x 1 = 1
LCM(689,401,613) = ( 689 × 401 × 613 ) / 1
LCM(689,401,613) = 169365157 / 1
LCM(689,401,613) = 169365157
