Lets's calculate GCF of 126,820
2 | 126, 820 |
63, 410 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 126
:1,2,3,6,7,9,14,18,21,42,63,126
Now, list down the factors of 820
:1,2,4,5,10,20,41,82,164,205,410,820
Greatest Common Factor
We found the factors 126,820 . The biggest common factor number is the GCF number.
So the greatest common factor 126,820 is 2.
Lets's calculate LCM of 812,173
Given numbers has no common factors except 1. So, there LCM is their product i.e 140476
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/140476
Therefore, the GCF of Fractions 126/812,820/173 is 2/140476
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 812,173 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(812,173) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(812,173) x common factors =1 x 1 = 1
LCM(812,173) = ( 812 × 173 ) / 1
LCM(812,173) = 140476 / 1
LCM(812,173) = 140476
