How to Find LCM of 2.8,6.3,7,7.2?
Given Numbers are 2.8,6.3,7,7.2
Given numbers are 2.8,6.3,7,7.2. 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
2.8 x 10 = 28
6.3 x 10 = 63
7 x 10 = 70
7.2 x 10 = 72
The LCM of 28,63,70,72 is 2520
So, the LCM of 2.8,6.3,7,7.2 is 252
| 2 | 28, 63, 70, 72 |
| 2 | 14, 63, 35, 36 |
| 3 | 7, 63, 35, 18 |
| 3 | 7, 21, 35, 6 |
| 7 | 7, 7, 35, 2 |
| 1, 1, 5, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 7 x 1 x 1 x 5 x 2 = 2520
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 2520/10 we get 252
Thus the Least Common Multiple of 2.8,6.3,7,7.2 is 252
Least Common Multiple of 28,63,70,72 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 28,63,70,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,63,70,72) = 1
common factors(in case of two or more numbers have common factors) = 3528
GCF(28,63,70,72) x common factors =1 x 3528 = 3528
LCM(28,63,70,72) = ( 28 × 63 × 70 × 72 ) / 3528
LCM(28,63,70,72) = 8890560 / 3528
LCM(28,63,70,72) = 2520
