Given numbers are 165,681,421

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

The LCM of 165,681,421 is 15768555.

Find LCM of 165,681,421 with Prime Factorization

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

3 x 55 x 227 x 421 = 15768555

Therefore, the lowest common multiple of 165,681,421 is 15768555.

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.

165 x 681 x 421 = 47305665

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.

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

681 : 1, 3, 227, 681

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,681,421, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

681:3x 227

421:421

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

3 = 3

Therefore, the value for common factors is 3.

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 = 47305665/(1x3)

LCM = 47305665/3

LCM = 15768555

Thus, we can understand that the LCM of 165,681,421 is 15768555.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 852, 708, 192
• LCM of 608, 776, 280
