Find LCM of 155,792,616,621 with Prime Factorization
| 2 | 155, 792, 616, 621 |
| 2 | 155, 396, 308, 621 |
| 2 | 155, 198, 154, 621 |
| 3 | 155, 99, 77, 621 |
| 3 | 155, 33, 77, 207 |
| 11 | 155, 11, 77, 69 |
| 155, 1, 7, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 11 x 155 x 1 x 7 x 69 = 59293080
Therefore, the lowest common multiple of 155,792,616,621 is 59293080.
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.
155 x 792 x 616 x 621 = 46960119360
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.
155 : 1, 5, 31, 155
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,792,616,621, is 1.
Now, the common factors can be found like this.
155:5x 31
792:2x 2x 2x 3x 3x 11
616:2x 2x 2x 7x 11
621:3x 3x 3x 23
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 3x 3x 11 = 792
Therefore, the value for common factors is 792.
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 = 46960119360/(1x792)
LCM = 46960119360/792
LCM = 59293080
Thus, we can understand that the LCM of 155,792,616,621 is 59293080.
