Lets's calculate GCF of 258,912
2 | 258, 912 |
3 | 129, 456 |
43, 152 |
∴ So the GCF of the given numbers is 2 x 3 = 6
Now, list down the factors of 258
:1,2,3,6,43,86,129,258
Now, list down the factors of 912
:1,2,3,4,6,8,12,16,19,24,38,48,57,76,114,152,228,304,456,912
Greatest Common Factor
We found the factors 258,912 . The biggest common factor number is the GCF number.
So the greatest common factor 258,912 is 6.
Lets's calculate LCM of 770,764
2 | 770, 764 |
385, 382 |
∴ So the LCM of the given numbers is 2 x 385 x 382 = 294140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/294140
Therefore, the GCF of Fractions 258/770,912/764 is 6/294140
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 770,764 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(770,764) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(770,764) x common factors =2 x 1 = 2
LCM(770,764) = ( 770 × 764 ) / 2
LCM(770,764) = 588280 / 2
LCM(770,764) = 294140
