Given numbers are 392,182,803,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,182,803,731 is 2991316328.
Find LCM of 392,182,803,731 with Prime Factorization
| 2 | 392, 182, 803, 731 |
| 7 | 196, 91, 803, 731 |
| 28, 13, 803, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 28 x 13 x 803 x 731 = 2991316328
Therefore, the lowest common multiple of 392,182,803,731 is 2991316328.
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.
392 x 182 x 803 x 731 = 41878428592
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
182 : 1, 2, 7, 13, 14, 26, 91, 182
803 : 1, 11, 73, 803
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,182,803,731, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
182:2x 7x 13
803:11x 73
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 41878428592/(1x14)
LCM = 41878428592/14
LCM = 2991316328
Thus, we can understand that the LCM of 392,182,803,731 is 2991316328.
