Given numbers are 160,974,900,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 160,974,900,489 is 571543200.
Find LCM of 160,974,900,489 with Prime Factorization
| 2 | 160, 974, 900, 489 |
| 2 | 80, 487, 450, 489 |
| 3 | 40, 487, 225, 489 |
| 5 | 40, 487, 75, 163 |
| 8, 487, 15, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 8 x 487 x 15 x 163 = 571543200
Therefore, the lowest common multiple of 160,974,900,489 is 571543200.
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.
160 x 974 x 900 x 489 = 68585184000
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.
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
974 : 1, 2, 487, 974
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,974,900,489, is 1.
Now, the common factors can be found like this.
160:2x 2x 2x 2x 2x 5
974:2x 487
900:2x 2x 3x 3x 5x 5
489:3x 163
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 68585184000/(1x120)
LCM = 68585184000/120
LCM = 571543200
Thus, we can understand that the LCM of 160,974,900,489 is 571543200.
