Greatest Common Factor
We found the factors 82,21,43,536 . The biggest common factor number is the GCF number.
So the greatest common factor 82,21,43,536 is 1.
Lets's calculate LCM of 88,81,98,72
2 | 88, 81, 98, 72 |
2 | 44, 81, 49, 36 |
2 | 22, 81, 49, 18 |
3 | 11, 81, 49, 9 |
3 | 11, 27, 49, 3 |
11, 9, 49, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 11 x 9 x 49 x 1 = 349272
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/349272
Therefore, the GCF of Fractions 82/88,21/81,43/98,536/72 is 1/349272
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 88,81,98,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(88,81,98,72) = 1
common factors(in case of two or more numbers have common factors) = 144
GCF(88,81,98,72) x common factors =1 x 144 = 144
LCM(88,81,98,72) = ( 88 × 81 × 98 × 72 ) / 144
LCM(88,81,98,72) = 50295168 / 144
LCM(88,81,98,72) = 349272
