Find LCM of 765,156,728,935 with Prime Factorization
| 2 | 765, 156, 728, 935 |
| 2 | 765, 78, 364, 935 |
| 3 | 765, 39, 182, 935 |
| 5 | 255, 13, 182, 935 |
| 13 | 51, 13, 182, 187 |
| 17 | 51, 1, 14, 187 |
| 3, 1, 14, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 17 x 3 x 1 x 14 x 11 = 6126120
Therefore, the lowest common multiple of 765,156,728,935 is 6126120.
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.
765 x 156 x 728 x 935 = 81232351200
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
935 : 1, 5, 11, 17, 55, 85, 187, 935
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,156,728,935, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
156:2x 2x 3x 13
728:2x 2x 2x 7x 13
935:5x 11x 17
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 3x 5x 13x 17 = 13260
Therefore, the value for common factors is 13260.
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 = 81232351200/(1x13260)
LCM = 81232351200/13260
LCM = 6126120
Thus, we can understand that the LCM of 765,156,728,935 is 6126120.
