1,2,3,4,5,6,8,9,10,12,15,16,18,20,24,30,36,40,45,48,60,72,80,90,120,144,180,240,360,720
Greatest Common Factor
We found the factors 52,74,720 . The biggest common factor number is the GCF number.
So the greatest common factor 52,74,720 is 2.
Lets's calculate LCM of 29,42,78
2 | 29, 42, 78 |
3 | 29, 21, 39 |
29, 7, 13 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 7 x 13 = 15834
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/15834
Therefore, the GCF of Fractions 52/29,74/42,720/78 is 2/15834
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 29,42,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(29,42,78) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(29,42,78) x common factors =1 x 6 = 6
LCM(29,42,78) = ( 29 × 42 × 78 ) / 6
LCM(29,42,78) = 95004 / 6
LCM(29,42,78) = 15834
