Given numbers are 778,86,405

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

The LCM of 778,86,405 is 13548870.

Find LCM of 778,86,405 with Prime Factorization

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

2 x 389 x 43 x 405 = 13548870

Therefore, the lowest common multiple of 778,86,405 is 13548870.

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.

778 x 86 x 405 = 27097740

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.

778 : 1, 2, 389, 778

86 : 1, 2, 43, 86

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,86,405, is 1.

Now, the common factors can be found like this.

778:2x 389

86:2x 43

405:3x 3x 3x 3x 5

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 = 27097740/(1x2)

LCM = 27097740/2

LCM = 13548870

Thus, we can understand that the LCM of 778,86,405 is 13548870.

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

• LCM of 469, 75, 981
• LCM of 965, 73, 967
