Greatest Common Factor
We found the factors 16,621,515 . The biggest common factor number is the GCF number.
So the greatest common factor 16,621,515 is 1.
Lets's calculate LCM of 77,36,68
2 | 77, 36, 68 |
2 | 77, 18, 34 |
77, 9, 17 |
∴ So the LCM of the given numbers is 2 x 2 x 77 x 9 x 17 = 47124
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/47124
Therefore, the GCF of Fractions 16/77,621/36,515/68 is 1/47124
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 77,36,68 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,36,68) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(77,36,68) x common factors =1 x 4 = 4
LCM(77,36,68) = ( 77 × 36 × 68 ) / 4
LCM(77,36,68) = 188496 / 4
LCM(77,36,68) = 47124
