Given numbers are 754,728,930,886,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,728,930,886,821 is 3570501447240.
Find LCM of 754,728,930,886,821 with Prime Factorization
| 2 | 754, 728, 930, 886, 821 |
| 13 | 377, 364, 465, 443, 821 |
| 29, 28, 465, 443, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 28 x 465 x 443 x 821 = 3570501447240
Therefore, the lowest common multiple of 754,728,930,886,821 is 3570501447240.
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.
754 x 728 x 930 x 886 x 821 = 371332150512960
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
886 : 1, 2, 443, 886
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,728,930,886,821, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
728:2x 2x 2x 7x 13
930:2x 3x 5x 31
886:2x 443
821:821
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 371332150512960/(1x104)
LCM = 371332150512960/104
LCM = 3570501447240
Thus, we can understand that the LCM of 754,728,930,886,821 is 3570501447240.
