The LCM of 782,404,404,985,460 is 155594540.
Find LCM of 782,404,404,985,460 with Prime Factorization
| 2 | 782, 404, 404, 985, 460 |
| 2 | 391, 202, 202, 985, 230 |
| 5 | 391, 101, 101, 985, 115 |
| 23 | 391, 101, 101, 197, 23 |
| 101 | 17, 101, 101, 197, 1 |
| 17, 1, 1, 197, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 101 x 17 x 1 x 1 x 197 x 1 = 155594540
Therefore, the lowest common multiple of 782,404,404,985,460 is 155594540.
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.
782 x 404 x 404 x 985 x 460 = 57831378627200
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
404 : 1, 2, 4, 101, 202, 404
404 : 1, 2, 4, 101, 202, 404
985 : 1, 5, 197, 985
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,404,404,985,460, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
404:2x 2x 101
404:2x 2x 101
985:5x 197
460:2x 2x 5x 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 2x 2x 5x 23x 101 = 371680
Therefore, the value for common factors is 371680.
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 = 57831378627200/(1x371680)
LCM = 57831378627200/371680
LCM = 155594540
Thus, we can understand that the LCM of 782,404,404,985,460 is 155594540.
