Lets's calculate GCF of 472,154
2 | 472, 154 |
236, 77 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 472
:1,2,4,8,59,118,236,472
Now, list down the factors of 154
:1,2,7,11,14,22,77,154
Greatest Common Factor
We found the factors 472,154 . The biggest common factor number is the GCF number.
So the greatest common factor 472,154 is 2.
Lets's calculate LCM of 42,642
2 | 42, 642 |
3 | 21, 321 |
7, 107 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 107 = 4494
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/4494
Therefore, the GCF of Fractions 472/42,154/642 is 2/4494
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 42,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,642) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(42,642) x common factors =6 x 1 = 6
LCM(42,642) = ( 42 × 642 ) / 6
LCM(42,642) = 26964 / 6
LCM(42,642) = 4494
