1,7,103,721
Greatest Common Factor
We found the factors 28,40,721 . The biggest common factor number is the GCF number.
So the greatest common factor 28,40,721 is 1.
Lets's calculate LCM of 563,137,513
Given numbers has no common factors except 1. So, there LCM is their product i.e 39568203
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/39568203
Therefore, the GCF of Fractions 28/563,40/137,721/513 is 1/39568203
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 563,137,513 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(563,137,513) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(563,137,513) x common factors =1 x 1 = 1
LCM(563,137,513) = ( 563 × 137 × 513 ) / 1
LCM(563,137,513) = 39568203 / 1
LCM(563,137,513) = 39568203
