Given numbers are 605,874,221,256,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,874,221,256,161 is 104704920320.
Find LCM of 605,874,221,256,161 with Prime Factorization
2 | 605, 874, 221, 256, 161 |
23 | 605, 437, 221, 128, 161 |
605, 19, 221, 128, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 605 x 19 x 221 x 128 x 7 = 104704920320
Therefore, the lowest common multiple of 605,874,221,256,161 is 104704920320.
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.
605 x 874 x 221 x 256 x 161 = 4816426334720
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.
605 : 1, 5, 11, 55, 121, 605
874 : 1, 2, 19, 23, 38, 46, 437, 874
221 : 1, 13, 17, 221
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,874,221,256,161, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
874:2x 19x 23
221:13x 17
256:2x 2x 2x 2x 2x 2x 2x 2
161:7x 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 23 = 46
Therefore, the value for common factors is 46.
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 = 4816426334720/(1x46)
LCM = 4816426334720/46
LCM = 104704920320
Thus, we can understand that the LCM of 605,874,221,256,161 is 104704920320.
