The LCM of 664,790,939,152,817 is 201211511640.
Find LCM of 664,790,939,152,817 with Prime Factorization
| 2 | 664, 790, 939, 152, 817 |
| 2 | 332, 395, 939, 76, 817 |
| 2 | 166, 395, 939, 38, 817 |
| 19 | 83, 395, 939, 19, 817 |
| 83, 395, 939, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 83 x 395 x 939 x 1 x 43 = 201211511640
Therefore, the lowest common multiple of 664,790,939,152,817 is 201211511640.
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.
664 x 790 x 939 x 152 x 817 = 61168299538560
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
790 : 1, 2, 5, 10, 79, 158, 395, 790
939 : 1, 3, 313, 939
152 : 1, 2, 4, 8, 19, 38, 76, 152
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,790,939,152,817, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
790:2x 5x 79
939:3x 313
152:2x 2x 2x 19
817:19x 43
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 19 = 304
Therefore, the value for common factors is 304.
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 = 61168299538560/(1x304)
LCM = 61168299538560/304
LCM = 201211511640
Thus, we can understand that the LCM of 664,790,939,152,817 is 201211511640.
