The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
The HCF of 140,140 is 140.
Lets's calculate GCF of 140,140
2 | 140, 140 |
2 | 70, 70 |
5 | 35, 35 |
7 | 7, 7 |
1, 1 |
∴ So the GCF of the given numbers is 2 x 2 x 5 x 7 = 140
Now, list down the factors of 140
:1,2,4,5,7,10,14,20,28,35,70,140
Now, list down the factors of 140
:1,2,4,5,7,10,14,20,28,35,70,140
Greatest Common Factor
We found the factors 140,140 . The biggest common factor number is the GCF number.
So the greatest common factor 140,140 is 140.
Lets's calculate LCM of 445,989
Given numbers has no common factors except 1. So, there LCM is their product i.e 440105
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 140/440105
Therefore, the GCF of Fractions 140/445,140/989 is 140/440105
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 445,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(445,989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(445,989) x common factors =1 x 1 = 1
LCM(445,989) = ( 445 × 989 ) / 1
LCM(445,989) = 440105 / 1
LCM(445,989) = 440105
