Given numbers are 396,770,724,704
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,770,724,704 is 40138560.
Find LCM of 396,770,724,704 with Prime Factorization
| 2 | 396, 770, 724, 704 |
| 2 | 198, 385, 362, 352 |
| 11 | 99, 385, 181, 176 |
| 9, 35, 181, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 9 x 35 x 181 x 16 = 40138560
Therefore, the lowest common multiple of 396,770,724,704 is 40138560.
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.
396 x 770 x 724 x 704 = 155416504320
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
724 : 1, 2, 4, 181, 362, 724
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,770,724,704, is 2.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
770:2x 5x 7x 11
724:2x 2x 181
704:2x 2x 2x 2x 2x 2x 11
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 2x 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 155416504320/(2x1936)
LCM = 155416504320/3872
LCM = 40138560
Thus, we can understand that the LCM of 396,770,724,704 is 40138560.
