So the greatest common factor 72,349,880 is 1.
Lets's calculate LCM of 34,51,787
17 | 34, 51, 787 |
2, 3, 787 |
∴ So the LCM of the given numbers is 17 x 2 x 3 x 787 = 80274
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/80274
Therefore, the GCF of Fractions 72/34,349/51,880/787 is 1/80274
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 34,51,787 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(34,51,787) = 1
common factors(in case of two or more numbers have common factors) = 17
GCF(34,51,787) x common factors =1 x 17 = 17
LCM(34,51,787) = ( 34 × 51 × 787 ) / 17
LCM(34,51,787) = 1364658 / 17
LCM(34,51,787) = 80274
