Given numbers are 609,404,628,644,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,404,628,644,394 is 175021891212.
Find LCM of 609,404,628,644,394 with Prime Factorization
| 2 | 609, 404, 628, 644, 394 |
| 2 | 609, 202, 314, 322, 197 |
| 7 | 609, 101, 157, 161, 197 |
| 87, 101, 157, 23, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 87 x 101 x 157 x 23 x 197 = 175021891212
Therefore, the lowest common multiple of 609,404,628,644,394 is 175021891212.
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.
609 x 404 x 628 x 644 x 394 = 39204903631488
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
404 : 1, 2, 4, 101, 202, 404
628 : 1, 2, 4, 157, 314, 628
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,404,628,644,394, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
404:2x 2x 101
628:2x 2x 157
644:2x 2x 7x 23
394:2x 197
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 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 39204903631488/(1x224)
LCM = 39204903631488/224
LCM = 175021891212
Thus, we can understand that the LCM of 609,404,628,644,394 is 175021891212.
