Given numbers are 731,989,460,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,989,460,100 is 1681300.
Find LCM of 731,989,460,100 with Prime Factorization
| 2 | 731, 989, 460, 100 |
| 2 | 731, 989, 230, 50 |
| 5 | 731, 989, 115, 25 |
| 23 | 731, 989, 23, 5 |
| 43 | 731, 43, 1, 5 |
| 17, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 43 x 17 x 1 x 1 x 5 = 1681300
Therefore, the lowest common multiple of 731,989,460,100 is 1681300.
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 989 x 460 x 100 = 33256114000
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
989 : 1, 23, 43, 989
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,989,460,100, is 1.
Now, the common factors can be found like this.
731:17x 43
989:23x 43
460:2x 2x 5x 23
100:2x 2x 5x 5
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 5x 23x 43 = 19780
Therefore, the value for common factors is 19780.
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 = 33256114000/(1x19780)
LCM = 33256114000/19780
LCM = 1681300
Thus, we can understand that the LCM of 731,989,460,100 is 1681300.
