Given numbers are 172,731,267,136
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,731,267,136 is 1561416.
Find LCM of 172,731,267,136 with Prime Factorization
| 2 | 172, 731, 267, 136 |
| 2 | 86, 731, 267, 68 |
| 17 | 43, 731, 267, 34 |
| 43 | 43, 43, 267, 2 |
| 1, 1, 267, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 43 x 1 x 1 x 267 x 2 = 1561416
Therefore, the lowest common multiple of 172,731,267,136 is 1561416.
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.
172 x 731 x 267 x 136 = 4565580384
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.
172 : 1, 2, 4, 43, 86, 172
731 : 1, 17, 43, 731
267 : 1, 3, 89, 267
136 : 1, 2, 4, 8, 17, 34, 68, 136
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,731,267,136, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
731:17x 43
267:3x 89
136:2x 2x 2x 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 17x 43 = 2924
Therefore, the value for common factors is 2924.
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 = 4565580384/(1x2924)
LCM = 4565580384/2924
LCM = 1561416
Thus, we can understand that the LCM of 172,731,267,136 is 1561416.
