We found the factors 66,90,278 . The biggest common factor number is the GCF number.
So the greatest common factor 66,90,278 is 2.
Lets's calculate LCM of 604,284,840
2 | 604, 284, 840 |
2 | 302, 142, 420 |
151, 71, 210 |
∴ So the LCM of the given numbers is 2 x 2 x 151 x 71 x 210 = 9005640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/9005640
Therefore, the GCF of Fractions 66/604,90/284,278/840 is 2/9005640
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 604,284,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(604,284,840) = 4
common factors(in case of two or more numbers have common factors) = 4
GCF(604,284,840) x common factors =4 x 4 = 16
LCM(604,284,840) = ( 604 × 284 × 840 ) / 16
LCM(604,284,840) = 144090240 / 16
LCM(604,284,840) = 9005640
