Greatest Common Factor
We found the factors 88,30,779 . The biggest common factor number is the GCF number.
So the greatest common factor 88,30,779 is 1.
Lets's calculate LCM of 80,207,480
2 | 80, 207, 480 |
2 | 40, 207, 240 |
2 | 20, 207, 120 |
2 | 10, 207, 60 |
3 | 5, 207, 30 |
5 | 5, 69, 10 |
1, 69, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 5 x 1 x 69 x 2 = 33120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33120
Therefore, the GCF of Fractions 88/80,30/207,779/480 is 1/33120
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 80,207,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,207,480) = 1
common factors(in case of two or more numbers have common factors) = 240
GCF(80,207,480) x common factors =1 x 240 = 240
LCM(80,207,480) = ( 80 × 207 × 480 ) / 240
LCM(80,207,480) = 7948800 / 240
LCM(80,207,480) = 33120
