Given numbers are 470,480,689,139,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,480,689,139,717 is 516381908640.
Find LCM of 470,480,689,139,717 with Prime Factorization
| 2 | 470, 480, 689, 139, 717 |
| 3 | 235, 240, 689, 139, 717 |
| 5 | 235, 80, 689, 139, 239 |
| 47, 16, 689, 139, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 47 x 16 x 689 x 139 x 239 = 516381908640
Therefore, the lowest common multiple of 470,480,689,139,717 is 516381908640.
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.
470 x 480 x 689 x 139 x 717 = 15491457259200
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
689 : 1, 13, 53, 689
139 : 1, 139
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,480,689,139,717, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
480:2x 2x 2x 2x 2x 3x 5
689:13x 53
139:139
717:3x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 15491457259200/(1x30)
LCM = 15491457259200/30
LCM = 516381908640
Thus, we can understand that the LCM of 470,480,689,139,717 is 516381908640.
