Given numbers are 709,721,393,468
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,721,393,468 is 31339975212.
Find LCM of 709,721,393,468 with Prime Factorization
| 3 | 709, 721, 393, 468 |
| 709, 721, 131, 156 |
Multiply the prime numbers at the bottom and the left side.
3 x 709 x 721 x 131 x 156 = 31339975212
Therefore, the lowest common multiple of 709,721,393,468 is 31339975212.
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.
709 x 721 x 393 x 468 = 94019925636
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.
709 : 1, 709
721 : 1, 7, 103, 721
393 : 1, 3, 131, 393
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,721,393,468, is 1.
Now, the common factors can be found like this.
709:709
721:7x 103
393:3x 131
468:2x 2x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 94019925636/(1x3)
LCM = 94019925636/3
LCM = 31339975212
Thus, we can understand that the LCM of 709,721,393,468 is 31339975212.
