Given numbers are 425,260,731,820,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 425,260,731,820,100 is 38962300.
Find LCM of 425,260,731,820,100 with Prime Factorization
| 2 | 425, 260, 731, 820, 100 |
| 2 | 425, 130, 731, 410, 50 |
| 5 | 425, 65, 731, 205, 25 |
| 5 | 85, 13, 731, 41, 5 |
| 17 | 17, 13, 731, 41, 1 |
| 1, 13, 43, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 17 x 1 x 13 x 43 x 41 x 1 = 38962300
Therefore, the lowest common multiple of 425,260,731,820,100 is 38962300.
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.
425 x 260 x 731 x 820 x 100 = 6623591000000
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.
425 : 1, 5, 17, 25, 85, 425
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
731 : 1, 17, 43, 731
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,260,731,820,100, is 1.
Now, the common factors can be found like this.
425:5x 5x 17
260:2x 2x 5x 13
731:17x 43
820:2x 2x 5x 41
100:2x 2x 5x 5
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 5x 5x 5x 5x 17 = 170000
Therefore, the value for common factors is 170000.
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 = 6623591000000/(1x170000)
LCM = 6623591000000/170000
LCM = 38962300
Thus, we can understand that the LCM of 425,260,731,820,100 is 38962300.
