The HCF of 633,420 is 3.
Lets's calculate GCF of 633,420
3 | 633, 420 |
211, 140 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 633
:1,3,211,633
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 633,420 . The biggest common factor number is the GCF number.
So the greatest common factor 633,420 is 3.
Lets's calculate LCM of 10,409
Given numbers has no common factors except 1. So, there LCM is their product i.e 4090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/4090
Therefore, the GCF of Fractions 633/10,420/409 is 3/4090
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 10,409 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,409) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(10,409) x common factors =1 x 1 = 1
LCM(10,409) = ( 10 × 409 ) / 1
LCM(10,409) = 4090 / 1
LCM(10,409) = 4090
