Given numbers are 731,323,598,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,323,598,780 is 249168660.
Find LCM of 731,323,598,780 with Prime Factorization
2 | 731, 323, 598, 780 |
13 | 731, 323, 299, 390 |
17 | 731, 323, 23, 30 |
43, 19, 23, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 43 x 19 x 23 x 30 = 249168660
Therefore, the lowest common multiple of 731,323,598,780 is 249168660.
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 323 x 598 x 780 = 110132547720
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
323 : 1, 17, 19, 323
598 : 1, 2, 13, 23, 26, 46, 299, 598
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,323,598,780, is 1.
Now, the common factors can be found like this.
731:17x 43
323:17x 19
598:2x 13x 23
780:2x 2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 110132547720/(1x442)
LCM = 110132547720/442
LCM = 249168660
Thus, we can understand that the LCM of 731,323,598,780 is 249168660.
