Lets's calculate GCF of 980,700
2 | 980, 700 |
2 | 490, 350 |
5 | 245, 175 |
7 | 49, 35 |
7, 5 |
∴ So the GCF of the given numbers is 2 x 2 x 5 x 7 = 140
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 700
:1,2,4,5,7,10,14,20,25,28,35,50,70,100,140,175,350,700
Greatest Common Factor
We found the factors 980,700 . The biggest common factor number is the GCF number.
So the greatest common factor 980,700 is 140.
Lets's calculate LCM of 946,902
2 | 946, 902 |
11 | 473, 451 |
43, 41 |
∴ So the LCM of the given numbers is 2 x 11 x 43 x 41 = 38786
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 140/38786
Therefore, the GCF of Fractions 980/946,700/902 is 140/38786
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 946,902 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(946,902) = 22
common factors(in case of two or more numbers have common factors) = 1
GCF(946,902) x common factors =22 x 1 = 22
LCM(946,902) = ( 946 × 902 ) / 22
LCM(946,902) = 853292 / 22
LCM(946,902) = 38786
