Lets's calculate GCF of 980,812
2 | 980, 812 |
2 | 490, 406 |
7 | 245, 203 |
35, 29 |
∴ So the GCF of the given numbers is 2 x 2 x 7 = 28
Now, list down the factors of 980
:1,2,4,5,7,10,14,20,28,35,49,70,98,140,196,245,490,980
Now, list down the factors of 812
:1,2,4,7,14,28,29,58,116,203,406,812
Greatest Common Factor
We found the factors 980,812 . The biggest common factor number is the GCF number.
So the greatest common factor 980,812 is 28.
Lets's calculate LCM of 67,700
Given numbers has no common factors except 1. So, there LCM is their product i.e 46900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 28/46900
Therefore, the GCF of Fractions 980/67,812/700 is 28/46900
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 67,700 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(67,700) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(67,700) x common factors =1 x 1 = 1
LCM(67,700) = ( 67 × 700 ) / 1
LCM(67,700) = 46900 / 1
LCM(67,700) = 46900
