Given numbers are 687,427,786,404

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

The LCM of 687,427,786,404 is 15525202476.

Find LCM of 687,427,786,404 with Prime Factorization

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

2 x 3 x 229 x 427 x 131 x 202 = 15525202476

Therefore, the lowest common multiple of 687,427,786,404 is 15525202476.

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.

687 x 427 x 786 x 404 = 93151214856

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.

687 : 1, 3, 229, 687

427 : 1, 7, 61, 427

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

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,427,786,404, is 1.

Now, the common factors can be found like this.

687:3x 229

427:7x 61

786:2x 3x 131

404:2x 2x 101

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 93151214856/(1x6)

LCM = 93151214856/6

LCM = 15525202476

Thus, we can understand that the LCM of 687,427,786,404 is 15525202476.
