The HCF of 82,68,836 is 2.
Lets's calculate GCF of 82,68,836
2 | 82, 68, 836 |
41, 34, 418 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 82
:1,2,41,82
Now, list down the factors of 68
:1,2,4,17,34,68
Now, list down the factors of 836
:1,2,4,11,19,22,38,44,76,209,418,836
Greatest Common Factor
We found the factors 82,68,836 . The biggest common factor number is the GCF number.
So the greatest common factor 82,68,836 is 2.
Lets's calculate LCM of 79,12,37
Given numbers has no common factors except 1. So, there LCM is their product i.e 35076
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/35076
Therefore, the GCF of Fractions 82/79,68/12,836/37 is 2/35076
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 79,12,37 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,12,37) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(79,12,37) x common factors =1 x 1 = 1
LCM(79,12,37) = ( 79 × 12 × 37 ) / 1
LCM(79,12,37) = 35076 / 1
LCM(79,12,37) = 35076
