Greatest Common Factor
We found the factors 405,1055 . The biggest common factor number is the GCF number.
So the greatest common factor 405,1055 is 5.
Lets's calculate LCM of 462,757
Given numbers has no common factors except 1. So, there LCM is their product i.e 349734
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/349734
Therefore, the GCF of Fractions 405/462,1055/757 is 5/349734
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 462,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(462,757) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(462,757) x common factors =1 x 1 = 1
LCM(462,757) = ( 462 × 757 ) / 1
LCM(462,757) = 349734 / 1
LCM(462,757) = 349734
