Greatest Common Factor
We found the factors 28,88,578 . The biggest common factor number is the GCF number.
So the greatest common factor 28,88,578 is 2.
Lets's calculate LCM of 65,26,572
2 | 65, 26, 572 |
13 | 65, 13, 286 |
5, 1, 22 |
∴ So the LCM of the given numbers is 2 x 13 x 5 x 1 x 22 = 2860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2860
Therefore, the GCF of Fractions 28/65,88/26,578/572 is 2/2860
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 65,26,572 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,26,572) = 13
common factors(in case of two or more numbers have common factors) = 26
GCF(65,26,572) x common factors =13 x 26 = 338
LCM(65,26,572) = ( 65 × 26 × 572 ) / 338
LCM(65,26,572) = 966680 / 338
LCM(65,26,572) = 2860
