Given numbers are 321,578,371,485,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,578,371,485,636 is 66769560060.
Find LCM of 321,578,371,485,636 with Prime Factorization
| 2 | 321, 578, 371, 485, 636 |
| 3 | 321, 289, 371, 485, 318 |
| 53 | 107, 289, 371, 485, 106 |
| 107, 289, 7, 485, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 53 x 107 x 289 x 7 x 485 x 2 = 66769560060
Therefore, the lowest common multiple of 321,578,371,485,636 is 66769560060.
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.
321 x 578 x 371 x 485 x 636 = 21232720099080
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.
321 : 1, 3, 107, 321
578 : 1, 2, 17, 34, 289, 578
371 : 1, 7, 53, 371
485 : 1, 5, 97, 485
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,578,371,485,636, is 1.
Now, the common factors can be found like this.
321:3x 107
578:2x 17x 17
371:7x 53
485:5x 97
636:2x 2x 3x 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 3x 53 = 318
Therefore, the value for common factors is 318.
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 = 21232720099080/(1x318)
LCM = 21232720099080/318
LCM = 66769560060
Thus, we can understand that the LCM of 321,578,371,485,636 is 66769560060.
