Greatest Common Factor
We found the factors 36,45,321 . The biggest common factor number is the GCF number.
So the greatest common factor 36,45,321 is 3.
Lets's calculate LCM of 91,28,940
2 | 91, 28, 940 |
2 | 91, 14, 470 |
7 | 91, 7, 235 |
13, 1, 235 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 13 x 1 x 235 = 85540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/85540
Therefore, the GCF of Fractions 36/91,45/28,321/940 is 3/85540
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 91,28,940 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,28,940) = 1
common factors(in case of two or more numbers have common factors) = 28
GCF(91,28,940) x common factors =1 x 28 = 28
LCM(91,28,940) = ( 91 × 28 × 940 ) / 28
LCM(91,28,940) = 2395120 / 28
LCM(91,28,940) = 85540
