The LCM of 578,493,689,272,265 is 461960720.
Find LCM of 578,493,689,272,265 with Prime Factorization
| 2 | 578, 493, 689, 272, 265 |
| 17 | 289, 493, 689, 136, 265 |
| 53 | 17, 29, 689, 8, 265 |
| 17, 29, 13, 8, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 53 x 17 x 29 x 13 x 8 x 5 = 461960720
Therefore, the lowest common multiple of 578,493,689,272,265 is 461960720.
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.
578 x 493 x 689 x 272 x 265 = 14151704696480
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.
578 : 1, 2, 17, 34, 289, 578
493 : 1, 17, 29, 493
689 : 1, 13, 53, 689
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
265 : 1, 5, 53, 265
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,493,689,272,265, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
493:17x 29
689:13x 53
272:2x 2x 2x 2x 17
265:5x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17x 53 = 30634
Therefore, the value for common factors is 30634.
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 = 14151704696480/(1x30634)
LCM = 14151704696480/30634
LCM = 461960720
Thus, we can understand that the LCM of 578,493,689,272,265 is 461960720.
