Given numbers are 842,104,476,578,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,104,476,578,790 is 34987137640.
Find LCM of 842,104,476,578,790 with Prime Factorization
| 2 | 842, 104, 476, 578, 790 |
| 2 | 421, 52, 238, 289, 395 |
| 17 | 421, 26, 119, 289, 395 |
| 421, 26, 7, 17, 395 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 421 x 26 x 7 x 17 x 395 = 34987137640
Therefore, the lowest common multiple of 842,104,476,578,790 is 34987137640.
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.
842 x 104 x 476 x 578 x 790 = 19033002876160
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.
842 : 1, 2, 421, 842
104 : 1, 2, 4, 8, 13, 26, 52, 104
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
578 : 1, 2, 17, 34, 289, 578
790 : 1, 2, 5, 10, 79, 158, 395, 790
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,104,476,578,790, is 2.
Now, the common factors can be found like this.
842:2x 421
104:2x 2x 2x 13
476:2x 2x 7x 17
578:2x 17x 17
790:2x 5x 79
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 17 = 272
Therefore, the value for common factors is 272.
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 = 19033002876160/(2x272)
LCM = 19033002876160/544
LCM = 34987137640
Thus, we can understand that the LCM of 842,104,476,578,790 is 34987137640.
