Given numbers are 517,456,423,197
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,456,423,197 is 139329432.
Find LCM of 517,456,423,197 with Prime Factorization
| 3 | 517, 456, 423, 197 |
| 47 | 517, 152, 141, 197 |
| 11, 152, 3, 197 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 11 x 152 x 3 x 197 = 139329432
Therefore, the lowest common multiple of 517,456,423,197 is 139329432.
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.
517 x 456 x 423 x 197 = 19645449912
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.
517 : 1, 11, 47, 517
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
423 : 1, 3, 9, 47, 141, 423
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,456,423,197, is 1.
Now, the common factors can be found like this.
517:11x 47
456:2x 2x 2x 3x 19
423:3x 3x 47
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 47 = 141
Therefore, the value for common factors is 141.
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 = 19645449912/(1x141)
LCM = 19645449912/141
LCM = 139329432
Thus, we can understand that the LCM of 517,456,423,197 is 139329432.
