:1,2,3,6,137,274,411,822
Greatest Common Factor
We found the factors 148,822 . The biggest common factor number is the GCF number.
So the greatest common factor 148,822 is 2.
Lets's calculate LCM of 542,640
2 | 542, 640 |
271, 320 |
∴ So the LCM of the given numbers is 2 x 271 x 320 = 173440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/173440
Therefore, the GCF of Fractions 148/542,822/640 is 2/173440
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 542,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(542,640) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(542,640) x common factors =2 x 1 = 2
LCM(542,640) = ( 542 × 640 ) / 2
LCM(542,640) = 346880 / 2
LCM(542,640) = 173440
