Given numbers are 230,772,128,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 230,772,128,161 is 19886720.
Find LCM of 230,772,128,161 with Prime Factorization
2 | 230, 772, 128, 161 |
2 | 115, 386, 64, 161 |
23 | 115, 193, 32, 161 |
5, 193, 32, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 5 x 193 x 32 x 7 = 19886720
Therefore, the lowest common multiple of 230,772,128,161 is 19886720.
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.
230 x 772 x 128 x 161 = 3659156480
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
772 : 1, 2, 4, 193, 386, 772
128 : 1, 2, 4, 8, 16, 32, 64, 128
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,772,128,161, is 1.
Now, the common factors can be found like this.
230:2x 5x 23
772:2x 2x 193
128:2x 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 2x 2x 23 = 184
Therefore, the value for common factors is 184.
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 = 3659156480/(1x184)
LCM = 3659156480/184
LCM = 19886720
Thus, we can understand that the LCM of 230,772,128,161 is 19886720.
