Given numbers are 756,172,663,436,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,172,663,436,847 is 94753310652.
Find LCM of 756,172,663,436,847 with Prime Factorization
| 2 | 756, 172, 663, 436, 847 |
| 2 | 378, 86, 663, 218, 847 |
| 3 | 189, 43, 663, 109, 847 |
| 7 | 63, 43, 221, 109, 847 |
| 9, 43, 221, 109, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 9 x 43 x 221 x 109 x 121 = 94753310652
Therefore, the lowest common multiple of 756,172,663,436,847 is 94753310652.
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.
756 x 172 x 663 x 436 x 847 = 31837112379072
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
172 : 1, 2, 4, 43, 86, 172
663 : 1, 3, 13, 17, 39, 51, 221, 663
436 : 1, 2, 4, 109, 218, 436
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,172,663,436,847, is 1.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
172:2x 2x 43
663:3x 13x 17
436:2x 2x 109
847:7x 11x 11
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 2x 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 31837112379072/(1x336)
LCM = 31837112379072/336
LCM = 94753310652
Thus, we can understand that the LCM of 756,172,663,436,847 is 94753310652.
