Given numbers are 920,731,974,425
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,731,974,425 is 1637586200.
Find LCM of 920,731,974,425 with Prime Factorization
| 2 | 920, 731, 974, 425 |
| 5 | 460, 731, 487, 425 |
| 17 | 92, 731, 487, 85 |
| 92, 43, 487, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 92 x 43 x 487 x 5 = 1637586200
Therefore, the lowest common multiple of 920,731,974,425 is 1637586200.
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.
920 x 731 x 974 x 425 = 278389654000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
731 : 1, 17, 43, 731
974 : 1, 2, 487, 974
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,731,974,425, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
731:17x 43
974:2x 487
425:5x 5x 17
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 17 = 170
Therefore, the value for common factors is 170.
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 = 278389654000/(1x170)
LCM = 278389654000/170
LCM = 1637586200
Thus, we can understand that the LCM of 920,731,974,425 is 1637586200.
