Given numbers are 155,755,864,870,753
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,755,864,870,753 is 147195355680.
Find LCM of 155,755,864,870,753 with Prime Factorization
| 2 | 155, 755, 864, 870, 753 |
| 3 | 155, 755, 432, 435, 753 |
| 5 | 155, 755, 144, 145, 251 |
| 31, 151, 144, 29, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 151 x 144 x 29 x 251 = 147195355680
Therefore, the lowest common multiple of 155,755,864,870,753 is 147195355680.
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.
155 x 755 x 864 x 870 x 753 = 66237910056000
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.
155 : 1, 5, 31, 155
755 : 1, 5, 151, 755
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
753 : 1, 3, 251, 753
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,755,864,870,753, is 1.
Now, the common factors can be found like this.
155:5x 31
755:5x 151
864:2x 2x 2x 2x 2x 3x 3x 3
870:2x 3x 5x 29
753:3x 251
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 66237910056000/(1x450)
LCM = 66237910056000/450
LCM = 147195355680
Thus, we can understand that the LCM of 155,755,864,870,753 is 147195355680.
