Given numbers are 662,410,697,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,410,697,356 is 410658460.
Find LCM of 662,410,697,356 with Prime Factorization
| 2 | 662, 410, 697, 356 |
| 41 | 331, 205, 697, 178 |
| 331, 5, 17, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 41 x 331 x 5 x 17 x 178 = 410658460
Therefore, the lowest common multiple of 662,410,697,356 is 410658460.
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.
662 x 410 x 697 x 356 = 67347987440
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.
662 : 1, 2, 331, 662
410 : 1, 2, 5, 10, 41, 82, 205, 410
697 : 1, 17, 41, 697
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,410,697,356, is 1.
Now, the common factors can be found like this.
662:2x 331
410:2x 5x 41
697:17x 41
356:2x 2x 89
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 41 = 164
Therefore, the value for common factors is 164.
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 = 67347987440/(1x164)
LCM = 67347987440/164
LCM = 410658460
Thus, we can understand that the LCM of 662,410,697,356 is 410658460.
