Given numbers are 409,190,862,165

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

The LCM of 409,190,862,165 is 1105269330.

Find LCM of 409,190,862,165 with Prime Factorization

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

2 x 5 x 409 x 19 x 431 x 33 = 1105269330

Therefore, the lowest common multiple of 409,190,862,165 is 1105269330.

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.

409 x 190 x 862 x 165 = 11052693300

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.

409 : 1, 409

190 : 1, 2, 5, 10, 19, 38, 95, 190

862 : 1, 2, 431, 862

165 : 1, 3, 5, 11, 15, 33, 55, 165

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,190,862,165, is 1.

Now, the common factors can be found like this.

409:409

190:2x 5x 19

862:2x 431

165:3x 5x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 11052693300/(1x10)

LCM = 11052693300/10

LCM = 1105269330

Thus, we can understand that the LCM of 409,190,862,165 is 1105269330.
