Given numbers are 453,691,529,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,691,529,391 is 2815015839.
Find LCM of 453,691,529,391 with Prime Factorization
| 23 | 453, 691, 529, 391 |
| 453, 691, 23, 17 |
Multiply the prime numbers at the bottom and the left side.
23 x 453 x 691 x 23 x 17 = 2815015839
Therefore, the lowest common multiple of 453,691,529,391 is 2815015839.
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.
453 x 691 x 529 x 391 = 64745364297
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.
453 : 1, 3, 151, 453
691 : 1, 691
529 : 1, 23, 529
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,691,529,391, is 1.
Now, the common factors can be found like this.
453:3x 151
691:691
529:23x 23
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.
23 = 23
Therefore, the value for common factors is 23.
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 = 64745364297/(1x23)
LCM = 64745364297/23
LCM = 2815015839
Thus, we can understand that the LCM of 453,691,529,391 is 2815015839.
