Given numbers are 638,175,900,286,185
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,175,900,286,185 is 966665700.
Find LCM of 638,175,900,286,185 with Prime Factorization
| 2 | 638, 175, 900, 286, 185 |
| 5 | 319, 175, 450, 143, 185 |
| 5 | 319, 35, 90, 143, 37 |
| 11 | 319, 7, 18, 143, 37 |
| 29, 7, 18, 13, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 11 x 29 x 7 x 18 x 13 x 37 = 966665700
Therefore, the lowest common multiple of 638,175,900,286,185 is 966665700.
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.
638 x 175 x 900 x 286 x 185 = 5316661350000
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
175 : 1, 5, 7, 25, 35, 175
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
185 : 1, 5, 37, 185
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,175,900,286,185, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
175:5x 5x 7
900:2x 2x 3x 3x 5x 5
286:2x 11x 13
185:5x 37
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 5x 5x 5x 11 = 5500
Therefore, the value for common factors is 5500.
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 = 5316661350000/(1x5500)
LCM = 5316661350000/5500
LCM = 966665700
Thus, we can understand that the LCM of 638,175,900,286,185 is 966665700.
