Lets's calculate GCF of 711,234
3 | 711, 234 |
3 | 237, 78 |
79, 26 |
∴ So the GCF of the given numbers is 3 x 3 = 9
Now, list down the factors of 711
:1,3,9,79,237,711
Now, list down the factors of 234
:1,2,3,6,9,13,18,26,39,78,117,234
Greatest Common Factor
We found the factors 711,234 . The biggest common factor number is the GCF number.
So the greatest common factor 711,234 is 9.
Lets's calculate LCM of 140,783
Given numbers has no common factors except 1. So, there LCM is their product i.e 109620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/109620
Therefore, the GCF of Fractions 711/140,234/783 is 9/109620
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 140,783 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(140,783) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(140,783) x common factors =1 x 1 = 1
LCM(140,783) = ( 140 × 783 ) / 1
LCM(140,783) = 109620 / 1
LCM(140,783) = 109620
