Given numbers are 454,715,696,847,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 454,715,696,847,638 is 8698249560.
Find LCM of 454,715,696,847,638 with Prime Factorization
| 2 | 454, 715, 696, 847, 638 |
| 11 | 227, 715, 348, 847, 319 |
| 29 | 227, 65, 348, 77, 29 |
| 227, 65, 12, 77, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 227 x 65 x 12 x 77 x 1 = 8698249560
Therefore, the lowest common multiple of 454,715,696,847,638 is 8698249560.
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.
454 x 715 x 696 x 847 x 638 = 122088630824160
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.
454 : 1, 2, 227, 454
715 : 1, 5, 11, 13, 55, 65, 143, 715
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
847 : 1, 7, 11, 77, 121, 847
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,715,696,847,638, is 1.
Now, the common factors can be found like this.
454:2x 227
715:5x 11x 13
696:2x 2x 2x 3x 29
847:7x 11x 11
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11x 11x 29 = 14036
Therefore, the value for common factors is 14036.
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 = 122088630824160/(1x14036)
LCM = 122088630824160/14036
LCM = 8698249560
Thus, we can understand that the LCM of 454,715,696,847,638 is 8698249560.
