Greatest Common Factor
We found the factors 36,42,12,75 . The biggest common factor number is the GCF number.
So the greatest common factor 36,42,12,75 is 3.
Lets's calculate LCM of 87,39,53,689
3 | 87, 39, 53, 689 |
13 | 29, 13, 53, 689 |
53 | 29, 1, 53, 53 |
29, 1, 1, 1 |
∴ So the LCM of the given numbers is 3 x 13 x 53 x 29 x 1 x 1 x 1 = 59943
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/59943
Therefore, the GCF of Fractions 36/87,42/39,12/53,75/689 is 3/59943
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 87,39,53,689 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,39,53,689) = 1
common factors(in case of two or more numbers have common factors) = 2067
GCF(87,39,53,689) x common factors =1 x 2067 = 2067
LCM(87,39,53,689) = ( 87 × 39 × 53 × 689 ) / 2067
LCM(87,39,53,689) = 123902181 / 2067
LCM(87,39,53,689) = 59943
