Find LCM of 655,328,578,280,411 with Prime Factorization
| 2 | 655, 328, 578, 280, 411 |
| 2 | 655, 164, 289, 140, 411 |
| 2 | 655, 82, 289, 70, 411 |
| 5 | 655, 41, 289, 35, 411 |
| 131, 41, 289, 7, 411 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 131 x 41 x 289 x 7 x 411 = 178629362520
Therefore, the lowest common multiple of 655,328,578,280,411 is 178629362520.
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.
655 x 328 x 578 x 280 x 411 = 14290349001600
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.
655 : 1, 5, 131, 655
328 : 1, 2, 4, 8, 41, 82, 164, 328
578 : 1, 2, 17, 34, 289, 578
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
411 : 1, 3, 137, 411
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,328,578,280,411, is 1.
Now, the common factors can be found like this.
655:5x 131
328:2x 2x 2x 41
578:2x 17x 17
280:2x 2x 2x 5x 7
411:3x 137
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 5 = 80
Therefore, the value for common factors is 80.
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 = 14290349001600/(1x80)
LCM = 14290349001600/80
LCM = 178629362520
Thus, we can understand that the LCM of 655,328,578,280,411 is 178629362520.
