Given numbers are 455,689,786

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

The LCM of 455,689,786 is 18954390.

Find LCM of 455,689,786 with Prime Factorization

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

13 x 35 x 53 x 786 = 18954390

Therefore, the lowest common multiple of 455,689,786 is 18954390.

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.

455 x 689 x 786 = 246407070

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

689 : 1, 13, 53, 689

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,689,786, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

689:13x 53

786:2x 3x 131

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

13 = 13

Therefore, the value for common factors is 13.

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 = 246407070/(1x13)

LCM = 246407070/13

LCM = 18954390

Thus, we can understand that the LCM of 455,689,786 is 18954390.

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

• LCM of 395, 815, 683
