The HCF of 543,420 is 3.
Lets's calculate GCF of 543,420
3 | 543, 420 |
181, 140 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 543
:1,3,181,543
Now, list down the factors of 420
:1,2,3,4,5,6,7,10,12,14,15,20,21,28,30,35,42,60,70,84,105,140,210,420
Greatest Common Factor
We found the factors 543,420 . The biggest common factor number is the GCF number.
So the greatest common factor 543,420 is 3.
Lets's calculate LCM of 15,313
Given numbers has no common factors except 1. So, there LCM is their product i.e 4695
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/4695
Therefore, the GCF of Fractions 543/15,420/313 is 3/4695
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 15,313 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,313) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(15,313) x common factors =1 x 1 = 1
LCM(15,313) = ( 15 × 313 ) / 1
LCM(15,313) = 4695 / 1
LCM(15,313) = 4695
