Given numbers are 396,748,220,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,748,220,338 is 5688540.
Find LCM of 396,748,220,338 with Prime Factorization
| 2 | 396, 748, 220, 338 |
| 2 | 198, 374, 110, 169 |
| 11 | 99, 187, 55, 169 |
| 9, 17, 5, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 9 x 17 x 5 x 169 = 5688540
Therefore, the lowest common multiple of 396,748,220,338 is 5688540.
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.
396 x 748 x 220 x 338 = 22026026880
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
338 : 1, 2, 13, 26, 169, 338
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,748,220,338, is 2.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
748:2x 2x 11x 17
220:2x 2x 5x 11
338:2x 13x 13
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 11x 11 = 1936
Therefore, the value for common factors is 1936.
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 = 22026026880/(2x1936)
LCM = 22026026880/3872
LCM = 5688540
Thus, we can understand that the LCM of 396,748,220,338 is 5688540.
