Find LCM of 320,742,620,418,539 with Prime Factorization
| 2 | 320, 742, 620, 418, 539 |
| 2 | 160, 371, 310, 209, 539 |
| 5 | 80, 371, 155, 209, 539 |
| 7 | 16, 371, 31, 209, 539 |
| 11 | 16, 53, 31, 209, 77 |
| 16, 53, 31, 19, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 16 x 53 x 31 x 19 x 7 = 5384308160
Therefore, the lowest common multiple of 320,742,620,418,539 is 5384308160.
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.
320 x 742 x 620 x 418 x 539 = 33167338265600
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
742 : 1, 2, 7, 14, 53, 106, 371, 742
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
418 : 1, 2, 11, 19, 22, 38, 209, 418
539 : 1, 7, 11, 49, 77, 539
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,742,620,418,539, is 1.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
742:2x 7x 53
620:2x 2x 5x 31
418:2x 11x 19
539:7x 7x 11
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 2x 5x 7x 11 = 6160
Therefore, the value for common factors is 6160.
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 = 33167338265600/(1x6160)
LCM = 33167338265600/6160
LCM = 5384308160
Thus, we can understand that the LCM of 320,742,620,418,539 is 5384308160.
