The LCM of 731,520,860,767 is 22427080.
Find LCM of 731,520,860,767 with Prime Factorization
| 2 | 731, 520, 860, 767 |
| 2 | 731, 260, 430, 767 |
| 5 | 731, 130, 215, 767 |
| 13 | 731, 26, 43, 767 |
| 43 | 731, 2, 43, 59 |
| 17, 2, 1, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 43 x 17 x 2 x 1 x 59 = 22427080
Therefore, the lowest common multiple of 731,520,860,767 is 22427080.
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.
731 x 520 x 860 x 767 = 250734754400
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.
731 : 1, 17, 43, 731
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,520,860,767, is 1.
Now, the common factors can be found like this.
731:17x 43
520:2x 2x 2x 5x 13
860:2x 2x 5x 43
767:13x 59
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 5x 13x 43 = 11180
Therefore, the value for common factors is 11180.
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 = 250734754400/(1x11180)
LCM = 250734754400/11180
LCM = 22427080
Thus, we can understand that the LCM of 731,520,860,767 is 22427080.
