Given numbers are 389,473,418

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

The LCM of 389,473,418 is 6991886.

Find LCM of 389,473,418 with Prime Factorization

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

11 x 389 x 43 x 38 = 6991886

Therefore, the lowest common multiple of 389,473,418 is 6991886.

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.

389 x 473 x 418 = 76910746

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.

389 : 1, 389

473 : 1, 11, 43, 473

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,473,418, is 1.

Now, the common factors can be found like this.

389:389

473:11x 43

418:2x 11x 19

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

11 = 11

Therefore, the value for common factors is 11.

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 = 76910746/(1x11)

LCM = 76910746/11

LCM = 6991886

Thus, we can understand that the LCM of 389,473,418 is 6991886.

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

• LCM of 810, 166, 278
• LCM of 801, 777, 110
