Calculate the LCM of 161,105,368

Given numbers are 161,105,368

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 161,105,368 is 38640.

Find LCM of 161,105,368 with Prime Factorization


7 161, 105, 368
23 23, 15, 368
1, 15, 16

Multiply the prime numbers at the bottom and the left side.

7 x 23 x 1 x 15 x 16 = 38640

Therefore, the lowest common multiple of 161,105,368 is 38640.

LCM Formula to Find Lowest Common Multiple of 161,105,368

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.

161 x 105 x 368 = 6221040

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.

161 : 1, 7, 23, 161

105 : 1, 3, 5, 7, 15, 21, 35, 105

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,105,368, is 1.

Now, the common factors can be found like this.

161:7x 23

105:3x 5x 7

368:2x 2x 2x 2x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 6221040/(1x161)

LCM = 6221040/161

LCM = 38640

Thus, we can understand that the LCM of 161,105,368 is 38640.
