Given numbers are 497,357,737,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,357,737,391 is 429656997.
Find LCM of 497,357,737,391 with Prime Factorization
| 7 | 497, 357, 737, 391 |
| 17 | 71, 51, 737, 391 |
| 71, 3, 737, 23 |
Multiply the prime numbers at the bottom and the left side.
7 x 17 x 71 x 3 x 737 x 23 = 429656997
Therefore, the lowest common multiple of 497,357,737,391 is 429656997.
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.
497 x 357 x 737 x 391 = 51129182643
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.
497 : 1, 7, 71, 497
357 : 1, 3, 7, 17, 21, 51, 119, 357
737 : 1, 11, 67, 737
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,357,737,391, is 1.
Now, the common factors can be found like this.
497:7x 71
357:3x 7x 17
737:11x 67
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 17 = 119
Therefore, the value for common factors is 119.
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 = 51129182643/(1x119)
LCM = 51129182643/119
LCM = 429656997
Thus, we can understand that the LCM of 497,357,737,391 is 429656997.
