Given numbers are 389,378,940

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

The LCM of 389,378,940 is 69109740.

Find LCM of 389,378,940 with Prime Factorization

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

2 x 389 x 189 x 470 = 69109740

Therefore, the lowest common multiple of 389,378,940 is 69109740.

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 378 x 940 = 138219480

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

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,378,940, is 1.

Now, the common factors can be found like this.

389:389

378:2x 3x 3x 3x 7

940:2x 2x 5x 47

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

2 = 2

Therefore, the value for common factors is 2.

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 = 138219480/(1x2)

LCM = 138219480/2

LCM = 69109740

Thus, we can understand that the LCM of 389,378,940 is 69109740.
