Given numbers are 397,403,632,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,403,632,408 is 5156829912.
Find LCM of 397,403,632,408 with Prime Factorization
| 2 | 397, 403, 632, 408 |
| 2 | 397, 403, 316, 204 |
| 2 | 397, 403, 158, 102 |
| 397, 403, 79, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 397 x 403 x 79 x 51 = 5156829912
Therefore, the lowest common multiple of 397,403,632,408 is 5156829912.
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.
397 x 403 x 632 x 408 = 41254639296
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.
397 : 1, 397
403 : 1, 13, 31, 403
632 : 1, 2, 4, 8, 79, 158, 316, 632
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,403,632,408, is 1.
Now, the common factors can be found like this.
397:397
403:13x 31
632:2x 2x 2x 79
408:2x 2x 2x 3x 17
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 2 = 8
Therefore, the value for common factors is 8.
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 = 41254639296/(1x8)
LCM = 41254639296/8
LCM = 5156829912
Thus, we can understand that the LCM of 397,403,632,408 is 5156829912.
