Given numbers are 403,306,429,897,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,306,429,897,970 is 15131735190.
Find LCM of 403,306,429,897,970 with Prime Factorization
| 2 | 403, 306, 429, 897, 970 |
| 3 | 403, 153, 429, 897, 485 |
| 13 | 403, 51, 143, 299, 485 |
| 31, 51, 11, 23, 485 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 51 x 11 x 23 x 485 = 15131735190
Therefore, the lowest common multiple of 403,306,429,897,970 is 15131735190.
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.
403 x 306 x 429 x 897 x 970 = 46030738447980
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.
403 : 1, 13, 31, 403
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
429 : 1, 3, 11, 13, 33, 39, 143, 429
897 : 1, 3, 13, 23, 39, 69, 299, 897
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,306,429,897,970, is 1.
Now, the common factors can be found like this.
403:13x 31
306:2x 3x 3x 17
429:3x 11x 13
897:3x 13x 23
970:2x 5x 97
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 3x 13x 13 = 3042
Therefore, the value for common factors is 3042.
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 = 46030738447980/(1x3042)
LCM = 46030738447980/3042
LCM = 15131735190
Thus, we can understand that the LCM of 403,306,429,897,970 is 15131735190.
