Given numbers are 175,290,422,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 175,290,422,638 is 23558150.
Find LCM of 175,290,422,638 with Prime Factorization
| 2 | 175, 290, 422, 638 |
| 5 | 175, 145, 211, 319 |
| 29 | 35, 29, 211, 319 |
| 35, 1, 211, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 35 x 1 x 211 x 11 = 23558150
Therefore, the lowest common multiple of 175,290,422,638 is 23558150.
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.
175 x 290 x 422 x 638 = 13663727000
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.
175 : 1, 5, 7, 25, 35, 175
290 : 1, 2, 5, 10, 29, 58, 145, 290
422 : 1, 2, 211, 422
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 175,290,422,638, is 1.
Now, the common factors can be found like this.
175:5x 5x 7
290:2x 5x 29
422:2x 211
638:2x 11x 29
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 29 = 580
Therefore, the value for common factors is 580.
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 = 13663727000/(1x580)
LCM = 13663727000/580
LCM = 23558150
Thus, we can understand that the LCM of 175,290,422,638 is 23558150.
