The LCM of 731,221,788,983,828 is 1523739795084.
Find LCM of 731,221,788,983,828 with Prime Factorization
| 2 | 731, 221, 788, 983, 828 |
| 2 | 731, 221, 394, 983, 414 |
| 17 | 731, 221, 197, 983, 207 |
| 43, 13, 197, 983, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 43 x 13 x 197 x 983 x 207 = 1523739795084
Therefore, the lowest common multiple of 731,221,788,983,828 is 1523739795084.
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.
731 x 221 x 788 x 983 x 828 = 103614306065712
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.
731 : 1, 17, 43, 731
221 : 1, 13, 17, 221
788 : 1, 2, 4, 197, 394, 788
983 : 1, 983
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,221,788,983,828, is 1.
Now, the common factors can be found like this.
731:17x 43
221:13x 17
788:2x 2x 197
983:983
828:2x 2x 3x 3x 23
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 17 = 68
Therefore, the value for common factors is 68.
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 = 103614306065712/(1x68)
LCM = 103614306065712/68
LCM = 1523739795084
Thus, we can understand that the LCM of 731,221,788,983,828 is 1523739795084.
