Given numbers are 425,426,990,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 425,426,990,387 is 256909950.
Find LCM of 425,426,990,387 with Prime Factorization
| 2 | 425, 426, 990, 387 |
| 3 | 425, 213, 495, 387 |
| 3 | 425, 71, 165, 129 |
| 5 | 425, 71, 55, 43 |
| 85, 71, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 85 x 71 x 11 x 43 = 256909950
Therefore, the lowest common multiple of 425,426,990,387 is 256909950.
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.
425 x 426 x 990 x 387 = 69365686500
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.
425 : 1, 5, 17, 25, 85, 425
426 : 1, 2, 3, 6, 71, 142, 213, 426
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,426,990,387, is 1.
Now, the common factors can be found like this.
425:5x 5x 17
426:2x 3x 71
990:2x 3x 3x 5x 11
387:3x 3x 43
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 5 = 270
Therefore, the value for common factors is 270.
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 = 69365686500/(1x270)
LCM = 69365686500/270
LCM = 256909950
Thus, we can understand that the LCM of 425,426,990,387 is 256909950.
