The LCM of 417,440,731,680 is 134123880.
Find LCM of 417,440,731,680 with Prime Factorization
| 2 | 417, 440, 731, 680 |
| 2 | 417, 220, 731, 340 |
| 2 | 417, 110, 731, 170 |
| 5 | 417, 55, 731, 85 |
| 17 | 417, 11, 731, 17 |
| 417, 11, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 417 x 11 x 43 x 1 = 134123880
Therefore, the lowest common multiple of 417,440,731,680 is 134123880.
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.
417 x 440 x 731 x 680 = 91204238400
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.
417 : 1, 3, 139, 417
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
731 : 1, 17, 43, 731
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,440,731,680, is 1.
Now, the common factors can be found like this.
417:3x 139
440:2x 2x 2x 5x 11
731:17x 43
680:2x 2x 2x 5x 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 2x 5x 17 = 680
Therefore, the value for common factors is 680.
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 = 91204238400/(1x680)
LCM = 91204238400/680
LCM = 134123880
Thus, we can understand that the LCM of 417,440,731,680 is 134123880.
