:1,7,97,679
Now, list down the factors of 621
:1,3,9,23,27,69,207,621
Greatest Common Factor
We found the factors 679,621 . The biggest common factor number is the GCF number.
So the greatest common factor 679,621 is 1.
Lets's calculate LCM of 480,601
Given numbers has no common factors except 1. So, there LCM is their product i.e 288480
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/288480
Therefore, the GCF of Fractions 679/480,621/601 is 1/288480
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 480,601 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(480,601) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(480,601) x common factors =1 x 1 = 1
LCM(480,601) = ( 480 × 601 ) / 1
LCM(480,601) = 288480 / 1
LCM(480,601) = 288480
