Given numbers are 850,221,605,256
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,221,605,256 is 171142400.
Find LCM of 850,221,605,256 with Prime Factorization
| 2 | 850, 221, 605, 256 |
| 5 | 425, 221, 605, 128 |
| 17 | 85, 221, 121, 128 |
| 5, 13, 121, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 5 x 13 x 121 x 128 = 171142400
Therefore, the lowest common multiple of 850,221,605,256 is 171142400.
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.
850 x 221 x 605 x 256 = 29094208000
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
221 : 1, 13, 17, 221
605 : 1, 5, 11, 55, 121, 605
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,221,605,256, is 1.
Now, the common factors can be found like this.
850:2x 5x 5x 17
221:13x 17
605:5x 11x 11
256:2x 2x 2x 2x 2x 2x 2x 2
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 29094208000/(1x170)
LCM = 29094208000/170
LCM = 171142400
Thus, we can understand that the LCM of 850,221,605,256 is 171142400.
