The LCM of 423,731,668,172 is 206554284.
Find LCM of 423,731,668,172 with Prime Factorization
| 2 | 423, 731, 668, 172 |
| 2 | 423, 731, 334, 86 |
| 43 | 423, 731, 167, 43 |
| 423, 17, 167, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 423 x 17 x 167 x 1 = 206554284
Therefore, the lowest common multiple of 423,731,668,172 is 206554284.
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.
423 x 731 x 668 x 172 = 35527336848
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.
423 : 1, 3, 9, 47, 141, 423
731 : 1, 17, 43, 731
668 : 1, 2, 4, 167, 334, 668
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,731,668,172, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
731:17x 43
668:2x 2x 167
172:2x 2x 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 2x 43 = 172
Therefore, the value for common factors is 172.
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 = 35527336848/(1x172)
LCM = 35527336848/172
LCM = 206554284
Thus, we can understand that the LCM of 423,731,668,172 is 206554284.
