The LCM of 598,820,644,315 is 15446340.
Find LCM of 598,820,644,315 with Prime Factorization
| 2 | 598, 820, 644, 315 |
| 2 | 299, 410, 322, 315 |
| 5 | 299, 205, 161, 315 |
| 7 | 299, 41, 161, 63 |
| 23 | 299, 41, 23, 9 |
| 13, 41, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 23 x 13 x 41 x 1 x 9 = 15446340
Therefore, the lowest common multiple of 598,820,644,315 is 15446340.
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.
598 x 820 x 644 x 315 = 99474429600
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.
598 : 1, 2, 13, 23, 26, 46, 299, 598
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,820,644,315, is 1.
Now, the common factors can be found like this.
598:2x 13x 23
820:2x 2x 5x 41
644:2x 2x 7x 23
315:3x 3x 5x 7
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 5x 7x 23 = 6440
Therefore, the value for common factors is 6440.
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 = 99474429600/(1x6440)
LCM = 99474429600/6440
LCM = 15446340
Thus, we can understand that the LCM of 598,820,644,315 is 15446340.
