Given numbers are 262,689,638,159
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 262,689,638,159 is 172755726.
Find LCM of 262,689,638,159 with Prime Factorization
| 2 | 262, 689, 638, 159 |
| 53 | 131, 689, 319, 159 |
| 131, 13, 319, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 53 x 131 x 13 x 319 x 3 = 172755726
Therefore, the lowest common multiple of 262,689,638,159 is 172755726.
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.
262 x 689 x 638 x 159 = 18312106956
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.
262 : 1, 2, 131, 262
689 : 1, 13, 53, 689
638 : 1, 2, 11, 22, 29, 58, 319, 638
159 : 1, 3, 53, 159
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,689,638,159, is 1.
Now, the common factors can be found like this.
262:2x 131
689:13x 53
638:2x 11x 29
159:3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 53 = 106
Therefore, the value for common factors is 106.
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 = 18312106956/(1x106)
LCM = 18312106956/106
LCM = 172755726
Thus, we can understand that the LCM of 262,689,638,159 is 172755726.
