Greatest Common Factor
We found the factors 42,22,38,53 . The biggest common factor number is the GCF number.
So the greatest common factor 42,22,38,53 is 1.
Lets's calculate LCM of 29,60,36,900
2 | 29, 60, 36, 900 |
2 | 29, 30, 18, 450 |
3 | 29, 15, 9, 225 |
3 | 29, 5, 3, 75 |
5 | 29, 5, 1, 25 |
29, 1, 1, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 29 x 1 x 1 x 5 = 26100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26100
Therefore, the GCF of Fractions 42/29,22/60,38/36,53/900 is 1/26100
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 29,60,36,900 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,60,36,900) = 1
common factors(in case of two or more numbers have common factors) = 2160
GCF(29,60,36,900) x common factors =1 x 2160 = 2160
LCM(29,60,36,900) = ( 29 × 60 × 36 × 900 ) / 2160
LCM(29,60,36,900) = 56376000 / 2160
LCM(29,60,36,900) = 26100
