Given numbers are 442,902,561,476
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,902,561,476 is 8372364.
Find LCM of 442,902,561,476 with Prime Factorization
| 2 | 442, 902, 561, 476 |
| 11 | 221, 451, 561, 238 |
| 17 | 221, 41, 51, 238 |
| 13, 41, 3, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 13 x 41 x 3 x 14 = 8372364
Therefore, the lowest common multiple of 442,902,561,476 is 8372364.
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.
442 x 902 x 561 x 476 = 106462980624
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
902 : 1, 2, 11, 22, 41, 82, 451, 902
561 : 1, 3, 11, 17, 33, 51, 187, 561
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,902,561,476, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
902:2x 11x 41
561:3x 11x 17
476:2x 2x 7x 17
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 17x 17 = 12716
Therefore, the value for common factors is 12716.
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 = 106462980624/(1x12716)
LCM = 106462980624/12716
LCM = 8372364
Thus, we can understand that the LCM of 442,902,561,476 is 8372364.
