Given numbers are 476,398,489,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,398,489,631 is 29227942716.
Find LCM of 476,398,489,631 with Prime Factorization
| 2 | 476, 398, 489, 631 |
| 238, 199, 489, 631 |
Multiply the prime numbers at the bottom and the left side.
2 x 238 x 199 x 489 x 631 = 29227942716
Therefore, the lowest common multiple of 476,398,489,631 is 29227942716.
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.
476 x 398 x 489 x 631 = 58455885432
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
398 : 1, 2, 199, 398
489 : 1, 3, 163, 489
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,398,489,631, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
398:2x 199
489:3x 163
631:631
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 58455885432/(1x2)
LCM = 58455885432/2
LCM = 29227942716
Thus, we can understand that the LCM of 476,398,489,631 is 29227942716.
