Find LCM of 880,620,478,392,806 with Prime Factorization
| 2 | 880, 620, 478, 392, 806 |
| 2 | 440, 310, 239, 196, 403 |
| 2 | 220, 155, 239, 98, 403 |
| 5 | 110, 155, 239, 49, 403 |
| 31 | 22, 31, 239, 49, 403 |
| 22, 1, 239, 49, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 31 x 22 x 1 x 239 x 49 x 13 = 4153189040
Therefore, the lowest common multiple of 880,620,478,392,806 is 4153189040.
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.
880 x 620 x 478 x 392 x 806 = 82399270553600
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.
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
478 : 1, 2, 239, 478
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
806 : 1, 2, 13, 26, 31, 62, 403, 806
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 880,620,478,392,806, is 2.
Now, the common factors can be found like this.
880:2x 2x 2x 2x 5x 11
620:2x 2x 5x 31
478:2x 239
392:2x 2x 2x 7x 7
806:2x 13x 31
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 2x 2x 5x 31 = 9920
Therefore, the value for common factors is 9920.
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 = 82399270553600/(2x9920)
LCM = 82399270553600/19840
LCM = 4153189040
Thus, we can understand that the LCM of 880,620,478,392,806 is 4153189040.
