Greatest Common Factor
We found the factors 30,69,42,252 . The biggest common factor number is the GCF number.
So the greatest common factor 30,69,42,252 is 3.
Lets's calculate LCM of 83,63,65,36
3 | 83, 63, 65, 36 |
3 | 83, 21, 65, 12 |
83, 7, 65, 4 |
∴ So the LCM of the given numbers is 3 x 3 x 83 x 7 x 65 x 4 = 1359540
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1359540
Therefore, the GCF of Fractions 30/83,69/63,42/65,252/36 is 3/1359540
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 83,63,65,36 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,63,65,36) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(83,63,65,36) x common factors =1 x 9 = 9
LCM(83,63,65,36) = ( 83 × 63 × 65 × 36 ) / 9
LCM(83,63,65,36) = 12235860 / 9
LCM(83,63,65,36) = 1359540
