Given numbers are 643,745,515,846,410
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,745,515,846,410 is 1711428225030.
Find LCM of 643,745,515,846,410 with Prime Factorization
| 2 | 643, 745, 515, 846, 410 |
| 5 | 643, 745, 515, 423, 205 |
| 643, 149, 103, 423, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 643 x 149 x 103 x 423 x 41 = 1711428225030
Therefore, the lowest common multiple of 643,745,515,846,410 is 1711428225030.
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.
643 x 745 x 515 x 846 x 410 = 85571411251500
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.
643 : 1, 643
745 : 1, 5, 149, 745
515 : 1, 5, 103, 515
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
410 : 1, 2, 5, 10, 41, 82, 205, 410
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,745,515,846,410, is 1.
Now, the common factors can be found like this.
643:643
745:5x 149
515:5x 103
846:2x 3x 3x 47
410:2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 85571411251500/(1x50)
LCM = 85571411251500/50
LCM = 1711428225030
Thus, we can understand that the LCM of 643,745,515,846,410 is 1711428225030.
