Now, list down the factors of 1717
:1,17,101,1717
Greatest Common Factor
We found the factors 7080,1717 . The biggest common factor number is the GCF number.
So the greatest common factor 7080,1717 is 1.
Lets's calculate LCM of 620,705
5 | 620, 705 |
124, 141 |
∴ So the LCM of the given numbers is 5 x 124 x 141 = 87420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/87420
Therefore, the GCF of Fractions 7080/620,1717/705 is 1/87420
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 620,705 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(620,705) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(620,705) x common factors =5 x 1 = 5
LCM(620,705) = ( 620 × 705 ) / 5
LCM(620,705) = 437100 / 5
LCM(620,705) = 87420
