Given numbers are 7,391,663,299
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,391,663,299 is 106743.
Find LCM of 7,391,663,299 with Prime Factorization
| 13 | 7, 391, 663, 299 |
| 17 | 7, 391, 51, 23 |
| 23 | 7, 23, 3, 23 |
| 7, 1, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 23 x 7 x 1 x 3 x 1 = 106743
Therefore, the lowest common multiple of 7,391,663,299 is 106743.
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.
7 x 391 x 663 x 299 = 542574669
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.
7 : 1, 7
391 : 1, 17, 23, 391
663 : 1, 3, 13, 17, 39, 51, 221, 663
299 : 1, 13, 23, 299
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,391,663,299, is 1.
Now, the common factors can be found like this.
7:7
391:17x 23
663:3x 13x 17
299:13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17x 23 = 5083
Therefore, the value for common factors is 5083.
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 = 542574669/(1x5083)
LCM = 542574669/5083
LCM = 106743
Thus, we can understand that the LCM of 7,391,663,299 is 106743.
