Least Common Multiple of 34/90,14/31,78/84,17/581

Given numbers are 34/90,14/31,78/84,17/581

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 34,14,78,17

Least Common Multiple of Numerators i.e. LCM of 34,14,78,17 is 9282.

GCF of Denominators means GCF of 90,31,84,581 as per the given fractions.

GCF of 90,31,84,581 is 1 as it is the largest common factor for these numbers.

Lets's calculate LCM of 34,14,78,17

LCM of Fractions 34/90,14/31,78/84,17/581 is 9282

2 34, 14, 78, 17
17 17, 7, 39, 17
1, 7, 39, 1

∴ So the LCM of the given numbers is 2 x 17 x 1 x 7 x 39 x 1 = 9282

Least Common Multiple of 34,14,78,17 with GCF Formula

Least Common Multiple of 34,14,78,17 with GCF Formula

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 34,14,78,17 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(34,14,78,17) = 1

common factors(in case of two or more numbers have common factors) = 68

GCF(34,14,78,17) x common factors =1 x 68 = 68

LCM(34,14,78,17) = ( 34 × 14 × 78 × 17 ) / 68

LCM(34,14,78,17) = 631176 / 68

LCM(34,14,78,17) = 9282


Lets's calculate GCF of 90,31,84,581

∴ So GCF of numbers is 1 because of no common factors present between them.

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 9282/1

Therefore the LCM of Fractions 34/90,14/31,78/84,17/581 is 9282
