Given numbers are 397,663,429,744,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,663,429,744,889 is 638337211512.
Find LCM of 397,663,429,744,889 with Prime Factorization
| 3 | 397, 663, 429, 744, 889 |
| 13 | 397, 221, 143, 248, 889 |
| 397, 17, 11, 248, 889 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 397 x 17 x 11 x 248 x 889 = 638337211512
Therefore, the lowest common multiple of 397,663,429,744,889 is 638337211512.
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 663 x 429 x 744 x 889 = 74685453746904
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
663 : 1, 3, 13, 17, 39, 51, 221, 663
429 : 1, 3, 11, 13, 33, 39, 143, 429
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,663,429,744,889, is 1.
Now, the common factors can be found like this.
397:397
663:3x 13x 17
429:3x 11x 13
744:2x 2x 2x 3x 31
889:7x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 74685453746904/(1x117)
LCM = 74685453746904/117
LCM = 638337211512
Thus, we can understand that the LCM of 397,663,429,744,889 is 638337211512.
