Given numbers are 400,255,721,264
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 400,255,721,264 is 161792400.
Find LCM of 400,255,721,264 with Prime Factorization
| 2 | 400, 255, 721, 264 |
| 2 | 200, 255, 721, 132 |
| 2 | 100, 255, 721, 66 |
| 3 | 50, 255, 721, 33 |
| 5 | 50, 85, 721, 11 |
| 10, 17, 721, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 10 x 17 x 721 x 11 = 161792400
Therefore, the lowest common multiple of 400,255,721,264 is 161792400.
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.
400 x 255 x 721 x 264 = 19415088000
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
255 : 1, 3, 5, 15, 17, 51, 85, 255
721 : 1, 7, 103, 721
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,255,721,264, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
255:3x 5x 17
721:7x 103
264:2x 2x 2x 3x 11
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 19415088000/(1x120)
LCM = 19415088000/120
LCM = 161792400
Thus, we can understand that the LCM of 400,255,721,264 is 161792400.
