Given numbers are 674,400,736,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 674,400,736,621 is 167421600.
Find LCM of 674,400,736,621 with Prime Factorization
| 2 | 674, 400, 736, 621 |
| 2 | 337, 200, 368, 621 |
| 2 | 337, 100, 184, 621 |
| 2 | 337, 50, 92, 621 |
| 23 | 337, 25, 46, 621 |
| 337, 25, 2, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 23 x 337 x 25 x 2 x 27 = 167421600
Therefore, the lowest common multiple of 674,400,736,621 is 167421600.
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.
674 x 400 x 736 x 621 = 123222297600
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.
674 : 1, 2, 337, 674
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,400,736,621, is 1.
Now, the common factors can be found like this.
674:2x 337
400:2x 2x 2x 2x 5x 5
736:2x 2x 2x 2x 2x 23
621:3x 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 2x 2x 2x 23 = 736
Therefore, the value for common factors is 736.
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 = 123222297600/(1x736)
LCM = 123222297600/736
LCM = 167421600
Thus, we can understand that the LCM of 674,400,736,621 is 167421600.
