Find LCM of 615,997,497,553,790 with Prime Factorization
| 5 | 615, 997, 497, 553, 790 |
| 7 | 123, 997, 497, 553, 158 |
| 79 | 123, 997, 71, 79, 158 |
| 123, 997, 71, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 79 x 123 x 997 x 71 x 1 x 2 = 48148609530
Therefore, the lowest common multiple of 615,997,497,553,790 is 48148609530.
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.
615 x 997 x 497 x 553 x 790 = 133130905350450
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
997 : 1, 997
497 : 1, 7, 71, 497
553 : 1, 7, 79, 553
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,997,497,553,790, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
997:997
497:7x 71
553:7x 79
790:2x 5x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 79 = 2765
Therefore, the value for common factors is 2765.
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 = 133130905350450/(1x2765)
LCM = 133130905350450/2765
LCM = 48148609530
Thus, we can understand that the LCM of 615,997,497,553,790 is 48148609530.
