Given numbers are 781,56,388

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

The LCM of 781,56,388 is 4242392.

Find LCM of 781,56,388 with Prime Factorization

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

2 x 2 x 781 x 14 x 97 = 4242392

Therefore, the lowest common multiple of 781,56,388 is 4242392.

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.

781 x 56 x 388 = 16969568

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.

781 : 1, 11, 71, 781

56 : 1, 2, 4, 7, 8, 14, 28, 56

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,56,388, is 1.

Now, the common factors can be found like this.

781:11x 71

56:2x 2x 2x 7

388:2x 2x 97

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 16969568/(1x4)

LCM = 16969568/4

LCM = 4242392

Thus, we can understand that the LCM of 781,56,388 is 4242392.

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

• LCM of 401, 44, 651
• LCM of 738, 47, 730
