Given numbers are 657,974,423,868,711
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,974,423,868,711 is 1031190741756.
Find LCM of 657,974,423,868,711 with Prime Factorization
| 2 | 657, 974, 423, 868, 711 |
| 3 | 657, 487, 423, 434, 711 |
| 3 | 219, 487, 141, 434, 237 |
| 73, 487, 47, 434, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 73 x 487 x 47 x 434 x 79 = 1031190741756
Therefore, the lowest common multiple of 657,974,423,868,711 is 1031190741756.
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.
657 x 974 x 423 x 868 x 711 = 167052900164472
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.
657 : 1, 3, 9, 73, 219, 657
974 : 1, 2, 487, 974
423 : 1, 3, 9, 47, 141, 423
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
711 : 1, 3, 9, 79, 237, 711
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,974,423,868,711, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
974:2x 487
423:3x 3x 47
868:2x 2x 7x 31
711:3x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 167052900164472/(1x162)
LCM = 167052900164472/162
LCM = 1031190741756
Thus, we can understand that the LCM of 657,974,423,868,711 is 1031190741756.
