Find LCM of 790,728,689,240,802 with Prime Factorization
| 2 | 790, 728, 689, 240, 802 |
| 2 | 395, 364, 689, 120, 401 |
| 2 | 395, 182, 689, 60, 401 |
| 5 | 395, 91, 689, 30, 401 |
| 13 | 79, 91, 689, 6, 401 |
| 79, 7, 53, 6, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 79 x 7 x 53 x 6 x 401 = 36669076080
Therefore, the lowest common multiple of 790,728,689,240,802 is 36669076080.
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 728 x 689 x 240 x 802 = 76271678246400
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
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
689 : 1, 13, 53, 689
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,728,689,240,802, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
728:2x 2x 2x 7x 13
689:13x 53
240:2x 2x 2x 2x 3x 5
802:2x 401
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 2x 5x 13 = 2080
Therefore, the value for common factors is 2080.
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 = 76271678246400/(1x2080)
LCM = 76271678246400/2080
LCM = 36669076080
Thus, we can understand that the LCM of 790,728,689,240,802 is 36669076080.
