Given numbers are 706,290,430,979,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 706,290,430,979,389 is 1676383787210.
Find LCM of 706,290,430,979,389 with Prime Factorization
| 2 | 706, 290, 430, 979, 389 |
| 5 | 353, 145, 215, 979, 389 |
| 353, 29, 43, 979, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 353 x 29 x 43 x 979 x 389 = 1676383787210
Therefore, the lowest common multiple of 706,290,430,979,389 is 1676383787210.
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.
706 x 290 x 430 x 979 x 389 = 33527675744200
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.
706 : 1, 2, 353, 706
290 : 1, 2, 5, 10, 29, 58, 145, 290
430 : 1, 2, 5, 10, 43, 86, 215, 430
979 : 1, 11, 89, 979
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,290,430,979,389, is 1.
Now, the common factors can be found like this.
706:2x 353
290:2x 5x 29
430:2x 5x 43
979:11x 89
389:389
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 5 = 20
Therefore, the value for common factors is 20.
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 = 33527675744200/(1x20)
LCM = 33527675744200/20
LCM = 1676383787210
Thus, we can understand that the LCM of 706,290,430,979,389 is 1676383787210.
