1,2,3,5,6,9,10,15,18,30,45,90
Greatest Common Factor
We found the factors 61,79,16,90 . The biggest common factor number is the GCF number.
So the greatest common factor 61,79,16,90 is 1.
Lets's calculate LCM of 12,46,92,56
2 | 12, 46, 92, 56 |
2 | 6, 23, 46, 28 |
23 | 3, 23, 23, 14 |
3, 1, 1, 14 |
∴ So the LCM of the given numbers is 2 x 2 x 23 x 3 x 1 x 1 x 14 = 3864
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3864
Therefore, the GCF of Fractions 61/12,79/46,16/92,90/56 is 1/3864
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 12,46,92,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,46,92,56) = 2
common factors(in case of two or more numbers have common factors) = 368
GCF(12,46,92,56) x common factors =2 x 368 = 736
LCM(12,46,92,56) = ( 12 × 46 × 92 × 56 ) / 736
LCM(12,46,92,56) = 2843904 / 736
LCM(12,46,92,56) = 3864
