Given numbers are 820,799,349,564,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,799,349,564,988 is 169435444620.
Find LCM of 820,799,349,564,988 with Prime Factorization
| 2 | 820, 799, 349, 564, 988 |
| 2 | 410, 799, 349, 282, 494 |
| 47 | 205, 799, 349, 141, 247 |
| 205, 17, 349, 3, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 47 x 205 x 17 x 349 x 3 x 247 = 169435444620
Therefore, the lowest common multiple of 820,799,349,564,988 is 169435444620.
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.
820 x 799 x 349 x 564 x 988 = 127415454354240
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
799 : 1, 17, 47, 799
349 : 1, 349
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,799,349,564,988, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
799:17x 47
349:349
564:2x 2x 3x 47
988:2x 2x 13x 19
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 47 = 752
Therefore, the value for common factors is 752.
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 = 127415454354240/(1x752)
LCM = 127415454354240/752
LCM = 169435444620
Thus, we can understand that the LCM of 820,799,349,564,988 is 169435444620.
