Given numbers are 902,638,371,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,638,371,609 is 29113854.
Find LCM of 902,638,371,609 with Prime Factorization
| 2 | 902, 638, 371, 609 |
| 7 | 451, 319, 371, 609 |
| 11 | 451, 319, 53, 87 |
| 29 | 41, 29, 53, 87 |
| 41, 1, 53, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 29 x 41 x 1 x 53 x 3 = 29113854
Therefore, the lowest common multiple of 902,638,371,609 is 29113854.
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.
902 x 638 x 371 x 609 = 130022471964
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
638 : 1, 2, 11, 22, 29, 58, 319, 638
371 : 1, 7, 53, 371
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,638,371,609, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
638:2x 11x 29
371:7x 53
609:3x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 29 = 4466
Therefore, the value for common factors is 4466.
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 = 130022471964/(1x4466)
LCM = 130022471964/4466
LCM = 29113854
Thus, we can understand that the LCM of 902,638,371,609 is 29113854.
