LCM of decimals calculator gives the LCM of Decimal numbers given 7.8, 15.6, 16.9 i.e. 202.8 the smallest number that divides all of them exactly.
Least Common Multiple (LCM) of 7.8, 15.6, 16.9 is 202.8.
LCM(7.8, 15.6, 16.9) = 202.8
LCM of 7.8, 15.6, 16.9
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 7.8,15.6,16.9. 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
7.8 x 10 = 78
15.6 x 10 = 156
16.9 x 10 = 169
On finding the LCM of 78,156,169 we get the Least Common Multiple as 2028
Least Common Multiple 7.8,15.6,16.9 is 202.8
| 2 | 78, 156, 169 |
| 3 | 39, 78, 169 |
| 13 | 13, 26, 169 |
| 1, 2, 13 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 2 x 13 = 2028
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 2028/10 we get 202.8
Thus the Least Common Multiple of 7.8,15.6,16.9 is 202.8
Least Common Multiple of 78,156,169 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 78,156,169 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,156,169) = 13
common factors(in case of two or more numbers have common factors) = 78
GCF(78,156,169) x common factors =13 x 78 = 1014
LCM(78,156,169) = ( 78 × 156 × 169 ) / 1014
LCM(78,156,169) = 2056392 / 1014
LCM(78,156,169) = 2028
