Given numbers are 478,465,899,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,465,899,403 is 83795790.
Find LCM of 478,465,899,403 with Prime Factorization
| 31 | 478, 465, 899, 403 |
| 478, 15, 29, 13 |
Multiply the prime numbers at the bottom and the left side.
31 x 478 x 15 x 29 x 13 = 83795790
Therefore, the lowest common multiple of 478,465,899,403 is 83795790.
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.
478 x 465 x 899 x 403 = 80527754190
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.
478 : 1, 2, 239, 478
465 : 1, 3, 5, 15, 31, 93, 155, 465
899 : 1, 29, 31, 899
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,465,899,403, is 1.
Now, the common factors can be found like this.
478:2x 239
465:3x 5x 31
899:29x 31
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
31x 31 = 961
Therefore, the value for common factors is 961.
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 = 80527754190/(1x961)
LCM = 80527754190/961
LCM = 83795790
Thus, we can understand that the LCM of 478,465,899,403 is 83795790.
