Find LCM of 790,405,252,938,924 with Prime Factorization
| 2 | 790, 405, 252, 938, 924 |
| 2 | 395, 405, 126, 469, 462 |
| 3 | 395, 405, 63, 469, 231 |
| 3 | 395, 135, 21, 469, 77 |
| 5 | 395, 45, 7, 469, 77 |
| 7 | 79, 9, 7, 469, 77 |
| 79, 9, 1, 67, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 79 x 9 x 1 x 67 x 11 = 660248820
Therefore, the lowest common multiple of 790,405,252,938,924 is 660248820.
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.
790 x 405 x 252 x 938 x 924 = 69880735108800
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
938 : 1, 2, 7, 14, 67, 134, 469, 938
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,405,252,938,924, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
405:3x 3x 3x 3x 5
252:2x 2x 3x 3x 7
938:2x 7x 67
924:2x 2x 3x 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 3x 3x 3x 5x 7x 7 = 105840
Therefore, the value for common factors is 105840.
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 = 69880735108800/(1x105840)
LCM = 69880735108800/105840
LCM = 660248820
Thus, we can understand that the LCM of 790,405,252,938,924 is 660248820.
