So the greatest common factor 278,168,738 is 2.
Lets's calculate LCM of 92,46,385
2 | 92, 46, 385 |
23 | 46, 23, 385 |
2, 1, 385 |
∴ So the LCM of the given numbers is 2 x 23 x 2 x 1 x 385 = 35420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/35420
Therefore, the GCF of Fractions 278/92,168/46,738/385 is 2/35420
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 92,46,385 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(92,46,385) = 1
common factors(in case of two or more numbers have common factors) = 46
GCF(92,46,385) x common factors =1 x 46 = 46
LCM(92,46,385) = ( 92 × 46 × 385 ) / 46
LCM(92,46,385) = 1629320 / 46
LCM(92,46,385) = 35420
