Given numbers are 921,806,456,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,806,456,403 is 56416776.
Find LCM of 921,806,456,403 with Prime Factorization
| 2 | 921, 806, 456, 403 |
| 3 | 921, 403, 228, 403 |
| 13 | 307, 403, 76, 403 |
| 31 | 307, 31, 76, 31 |
| 307, 1, 76, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 307 x 1 x 76 x 1 = 56416776
Therefore, the lowest common multiple of 921,806,456,403 is 56416776.
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.
921 x 806 x 456 x 403 = 136415764368
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.
921 : 1, 3, 307, 921
806 : 1, 2, 13, 26, 31, 62, 403, 806
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,806,456,403, is 1.
Now, the common factors can be found like this.
921:3x 307
806:2x 13x 31
456:2x 2x 2x 3x 19
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.
2x 3x 13x 31 = 2418
Therefore, the value for common factors is 2418.
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 = 136415764368/(1x2418)
LCM = 136415764368/2418
LCM = 56416776
Thus, we can understand that the LCM of 921,806,456,403 is 56416776.
