Greatest Common Factor
We found the factors 87,87,86,86 . The biggest common factor number is the GCF number.
So the greatest common factor 87,87,86,86 is 1.
Lets's calculate LCM of 58,49,83,670
2 | 58, 49, 83, 670 |
29, 49, 83, 335 |
∴ So the LCM of the given numbers is 2 x 29 x 49 x 83 x 335 = 79021810
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/79021810
Therefore, the GCF of Fractions 87/58,87/49,86/83,86/670 is 1/79021810
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 58,49,83,670 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(58,49,83,670) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(58,49,83,670) x common factors =1 x 2 = 2
LCM(58,49,83,670) = ( 58 × 49 × 83 × 670 ) / 2
LCM(58,49,83,670) = 158043620 / 2
LCM(58,49,83,670) = 79021810
