# Least Common Multiple of 2.1, 2.8, 3, 9.8

LCM of decimals calculator gives the LCM of Decimal numbers given 2.1, 2.8, 3, 9.8 i.e. 294 the smallest number that divides all of them exactly.

Least Common Multiple (LCM) of 2.1, 2.8, 3, 9.8 is 294.

LCM(2.1, 2.8, 3, 9.8) = 294

## LCM of 2.1, 2.8, 3, 9.8

Enter two or more decimals separated by "commas"

Ex: 0.2, 0.3 or 0.4, 0.5, 0.6

LCM of:

Given numbers are 2.1,2.8,3,9.8. The highest number of digits after the decimal point in the given case is 1

Thus, in order to get rid of the decimal point we need to multiply them with 10. On doing so, they are as follows

2.1 x 10 = 21

2.8 x 10 = 28

3 x 10 = 30

9.8 x 10 = 98

On finding the LCM of 21,28,30,98 we get the Least Common Multiple as 2940

### Least Common Multiple (LCM) of 21,28,30,98 By Common Division

 2 21, 28, 30, 98 3 21, 14, 15, 49 7 7, 14, 5, 49 1, 2, 5, 7

∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 2 x 5 x 7 = 2940

Divide the result you got with the number you multiplied to make it as integer in the first step. In this case, we need to divide by 10 as we used it to make the given numbers into integers.

On dividing the LCM 2940/10 we get 294

Thus the Least Common Multiple of 2.1,2.8,3,9.8 is 294

Least Common Multiple of 21,28,30,98 with GCF Formula

### Least Common Multiple of 21,28,30,98 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 21,28,30,98 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,28,30,98) = 1

common factors(in case of two or more numbers have common factors) = 588

GCF(21,28,30,98) x common factors =1 x 588 = 588

LCM(21,28,30,98) = ( 21 × 28 × 30 × 98 ) / 588

LCM(21,28,30,98) = 1728720 / 588

LCM(21,28,30,98) = 2940
