Given numbers are 709,927,621,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,927,621,391 is 770946039.
Find LCM of 709,927,621,391 with Prime Factorization
| 3 | 709, 927, 621, 391 |
| 3 | 709, 309, 207, 391 |
| 23 | 709, 103, 69, 391 |
| 709, 103, 3, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 709 x 103 x 3 x 17 = 770946039
Therefore, the lowest common multiple of 709,927,621,391 is 770946039.
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 927 x 621 x 391 = 159585830073
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
927 : 1, 3, 9, 103, 309, 927
621 : 1, 3, 9, 23, 27, 69, 207, 621
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,927,621,391, is 1.
Now, the common factors can be found like this.
709:709
927:3x 3x 103
621:3x 3x 3x 23
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 159585830073/(1x207)
LCM = 159585830073/207
LCM = 770946039
Thus, we can understand that the LCM of 709,927,621,391 is 770946039.
