Greatest Common Factor
We found the factors 83,94,70,62,130,22,37,968,22,20 . The biggest common factor number is the GCF number.
So the greatest common factor 83,94,70,62,130,22,37,968,22,20 is 1.
Lets's calculate LCM of 1,8,9,1,8,4,1,3,8,2
2 | 1, 8, 9, 1, 8, 4, 1, 3, 8, 2 |
2 | 1, 4, 9, 1, 4, 2, 1, 3, 4, 1 |
2 | 1, 1, 9, 1, 2, 2, 1, 3, 2, 1 |
3 | 1, 1, 9, 1, 1, 1, 1, 3, 1, 1 |
1, 1, 1, 1, 1, 1, 1, 3, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 3 x 1 x 1 = 72
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/72
Therefore, the GCF of Fractions 83/1,94/8,70/9,62/1,130/8,22/4,37/1,968/3,22/8,20/2 is 1/72
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 1,8,9,1,8,4,1,3,8,2 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(1,8,9,1,8,4,1,3,8,2) = 1
common factors(in case of two or more numbers have common factors) = 1536
GCF(1,8,9,1,8,4,1,3,8,2) x common factors =1 x 1536 = 1536
LCM(1,8,9,1,8,4,1,3,8,2) = ( 1 × 8 × 9 × 1 × 8 × 4 × 1 × 3 × 8 × 2 ) / 1536
LCM(1,8,9,1,8,4,1,3,8,2) = 110592 / 1536
LCM(1,8,9,1,8,4,1,3,8,2) = 72
