Given numbers are 215,740,161,887,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,740,161,887,720 is 163588274640.
Find LCM of 215,740,161,887,720 with Prime Factorization
| 2 | 215, 740, 161, 887, 720 |
| 2 | 215, 370, 161, 887, 360 |
| 5 | 215, 185, 161, 887, 180 |
| 43, 37, 161, 887, 36 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 37 x 161 x 887 x 36 = 163588274640
Therefore, the lowest common multiple of 215,740,161,887,720 is 163588274640.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
215 x 740 x 161 x 887 x 720 = 16358827464000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
215 : 1, 5, 43, 215
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
161 : 1, 7, 23, 161
887 : 1, 887
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,740,161,887,720, is 1.
Now, the common factors can be found like this.
215:5x 43
740:2x 2x 5x 37
161:7x 23
887:887
720:2x 2x 2x 2x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5 = 100
Therefore, the value for common factors is 100.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 16358827464000/(1x100)
LCM = 16358827464000/100
LCM = 163588274640
Thus, we can understand that the LCM of 215,740,161,887,720 is 163588274640.
