Given numbers are 397,647,357,444,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,647,357,444,988 is 3352136324628.
Find LCM of 397,647,357,444,988 with Prime Factorization
| 2 | 397, 647, 357, 444, 988 |
| 2 | 397, 647, 357, 222, 494 |
| 3 | 397, 647, 357, 111, 247 |
| 397, 647, 119, 37, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 397 x 647 x 119 x 37 x 247 = 3352136324628
Therefore, the lowest common multiple of 397,647,357,444,988 is 3352136324628.
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.
397 x 647 x 357 x 444 x 988 = 40225635895536
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.
397 : 1, 397
647 : 1, 647
357 : 1, 3, 7, 17, 21, 51, 119, 357
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,647,357,444,988, is 1.
Now, the common factors can be found like this.
397:397
647:647
357:3x 7x 17
444:2x 2x 3x 37
988:2x 2x 13x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 40225635895536/(1x12)
LCM = 40225635895536/12
LCM = 3352136324628
Thus, we can understand that the LCM of 397,647,357,444,988 is 3352136324628.
