Given numbers are 209,428,561,862

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

The LCM of 209,428,561,862 is 1966244412.

Find LCM of 209,428,561,862 with Prime Factorization

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

2 x 11 x 19 x 214 x 51 x 431 = 1966244412

Therefore, the lowest common multiple of 209,428,561,862 is 1966244412.

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.

209 x 428 x 561 x 862 = 43257377064

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.

209 : 1, 11, 19, 209

428 : 1, 2, 4, 107, 214, 428

561 : 1, 3, 11, 17, 33, 51, 187, 561

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,428,561,862, is 1.

Now, the common factors can be found like this.

209:11x 19

428:2x 2x 107

561:3x 11x 17

862:2x 431

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 43257377064/(1x22)

LCM = 43257377064/22

LCM = 1966244412

Thus, we can understand that the LCM of 209,428,561,862 is 1966244412.
