Given numbers are 165,766,931,442,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,766,931,442,418 is 26004868890.
Find LCM of 165,766,931,442,418 with Prime Factorization
| 2 | 165, 766, 931, 442, 418 |
| 11 | 165, 383, 931, 221, 209 |
| 19 | 15, 383, 931, 221, 19 |
| 15, 383, 49, 221, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 15 x 383 x 49 x 221 x 1 = 26004868890
Therefore, the lowest common multiple of 165,766,931,442,418 is 26004868890.
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.
165 x 766 x 931 x 442 x 418 = 21740070392040
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
766 : 1, 2, 383, 766
931 : 1, 7, 19, 49, 133, 931
442 : 1, 2, 13, 17, 26, 34, 221, 442
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,766,931,442,418, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
766:2x 383
931:7x 7x 19
442:2x 13x 17
418:2x 11x 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 11x 19 = 836
Therefore, the value for common factors is 836.
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 = 21740070392040/(1x836)
LCM = 21740070392040/836
LCM = 26004868890
Thus, we can understand that the LCM of 165,766,931,442,418 is 26004868890.
