1,2,4,5,8,10,16,20,40,80
Factors of 38
List of positive integer factors of 38 that divides 38 without a remainder.
1,2,19,38
Factors of 117
List of positive integer factors of 117 that divides 117 without a remainder.
1,3,9,13,39,117
Greatest Common Factor
We found the factors 80,38,117 . The biggest common factor number is the GCF number.
So the greatest common factor 80,38,117 is 1.
Lets's calculate LCM of 98,51,340
2 | 98, 51, 340 |
17 | 49, 51, 170 |
49, 3, 10 |
∴ So the LCM of the given numbers is 2 x 17 x 49 x 3 x 10 = 49980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/49980
Therefore, the GCF of Fractions 80/98,38/51,117/340 is 1/49980
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 98,51,340 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,51,340) = 1
common factors(in case of two or more numbers have common factors) = 34
GCF(98,51,340) x common factors =1 x 34 = 34
LCM(98,51,340) = ( 98 × 51 × 340 ) / 34
LCM(98,51,340) = 1699320 / 34
LCM(98,51,340) = 49980
