Greatest Common Factor
We found the factors 28,74,712 . The biggest common factor number is the GCF number.
So the greatest common factor 28,74,712 is 2.
Lets's calculate LCM of 655,178,556
2 | 655, 178, 556 |
655, 89, 278 |
∴ So the LCM of the given numbers is 2 x 655 x 89 x 278 = 32412020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/32412020
Therefore, the GCF of Fractions 28/655,74/178,712/556 is 2/32412020
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 655,178,556 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(655,178,556) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(655,178,556) x common factors =1 x 2 = 2
LCM(655,178,556) = ( 655 × 178 × 556 ) / 2
LCM(655,178,556) = 64824040 / 2
LCM(655,178,556) = 32412020
