Given numbers are 234,988,780,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 234,988,780,631 is 28054260.
Find LCM of 234,988,780,631 with Prime Factorization
| 2 | 234, 988, 780, 631 |
| 2 | 117, 494, 390, 631 |
| 3 | 117, 247, 195, 631 |
| 13 | 39, 247, 65, 631 |
| 3, 19, 5, 631 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 3 x 19 x 5 x 631 = 28054260
Therefore, the lowest common multiple of 234,988,780,631 is 28054260.
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.
234 x 988 x 780 x 631 = 113788078560
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.
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
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
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 234,988,780,631, is 1.
Now, the common factors can be found like this.
234:2x 3x 3x 13
988:2x 2x 13x 19
780:2x 2x 3x 5x 13
631:631
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 3x 13x 13 = 4056
Therefore, the value for common factors is 4056.
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 = 113788078560/(1x4056)
LCM = 113788078560/4056
LCM = 28054260
Thus, we can understand that the LCM of 234,988,780,631 is 28054260.
