1,2,4,8,11,22,44,88,121,242,484,968
Greatest Common Factor
We found the factors 13,28,19,968 . The biggest common factor number is the GCF number.
So the greatest common factor 13,28,19,968 is 1.
Lets's calculate LCM of 36,22,77,66
2 | 36, 22, 77, 66 |
3 | 18, 11, 77, 33 |
11 | 6, 11, 77, 11 |
6, 1, 7, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 11 x 6 x 1 x 7 x 1 = 2772
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2772
Therefore, the GCF of Fractions 13/36,28/22,19/77,968/66 is 1/2772
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 36,22,77,66 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,22,77,66) = 1
common factors(in case of two or more numbers have common factors) = 1452
GCF(36,22,77,66) x common factors =1 x 1452 = 1452
LCM(36,22,77,66) = ( 36 × 22 × 77 × 66 ) / 1452
LCM(36,22,77,66) = 4024944 / 1452
LCM(36,22,77,66) = 2772
