Given numbers are 639,135,324,374,125
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,135,324,374,125 is 537718500.
Find LCM of 639,135,324,374,125 with Prime Factorization
| 2 | 639, 135, 324, 374, 125 |
| 3 | 639, 135, 162, 187, 125 |
| 3 | 213, 45, 54, 187, 125 |
| 3 | 71, 15, 18, 187, 125 |
| 5 | 71, 5, 6, 187, 125 |
| 71, 1, 6, 187, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 71 x 1 x 6 x 187 x 25 = 537718500
Therefore, the lowest common multiple of 639,135,324,374,125 is 537718500.
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.
639 x 135 x 324 x 374 x 125 = 1306655955000
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.
639 : 1, 3, 9, 71, 213, 639
135 : 1, 3, 5, 9, 15, 27, 45, 135
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
374 : 1, 2, 11, 17, 22, 34, 187, 374
125 : 1, 5, 25, 125
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,135,324,374,125, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
135:3x 3x 3x 5
324:2x 2x 3x 3x 3x 3
374:2x 11x 17
125:5x 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 3x 3x 3x 3x 3x 5 = 2430
Therefore, the value for common factors is 2430.
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 = 1306655955000/(1x2430)
LCM = 1306655955000/2430
LCM = 537718500
Thus, we can understand that the LCM of 639,135,324,374,125 is 537718500.
