Given numbers are 158,589,552,687,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 158,589,552,687,646 is 99992141016.
Find LCM of 158,589,552,687,646 with Prime Factorization
| 2 | 158, 589, 552, 687, 646 |
| 3 | 79, 589, 276, 687, 323 |
| 19 | 79, 589, 92, 229, 323 |
| 79, 31, 92, 229, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 79 x 31 x 92 x 229 x 17 = 99992141016
Therefore, the lowest common multiple of 158,589,552,687,646 is 99992141016.
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.
158 x 589 x 552 x 687 x 646 = 22798208151648
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.
158 : 1, 2, 79, 158
589 : 1, 19, 31, 589
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
687 : 1, 3, 229, 687
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,589,552,687,646, is 1.
Now, the common factors can be found like this.
158:2x 79
589:19x 31
552:2x 2x 2x 3x 23
687:3x 229
646:2x 17x 19
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 22798208151648/(1x228)
LCM = 22798208151648/228
LCM = 99992141016
Thus, we can understand that the LCM of 158,589,552,687,646 is 99992141016.
