Given numbers are 176,209,861,421

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

The LCM of 176,209,861,421 is 1212136464.

Find LCM of 176,209,861,421 with Prime Factorization

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

11 x 16 x 19 x 861 x 421 = 1212136464

Therefore, the lowest common multiple of 176,209,861,421 is 1212136464.

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.

176 x 209 x 861 x 421 = 13333501104

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.

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

209 : 1, 11, 19, 209

861 : 1, 3, 7, 21, 41, 123, 287, 861

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 176,209,861,421, is 1.

Now, the common factors can be found like this.

176:2x 2x 2x 2x 11

209:11x 19

861:3x 7x 41

421:421

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

11 = 11

Therefore, the value for common factors is 11.

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 = 13333501104/(1x11)

LCM = 13333501104/11

LCM = 1212136464

Thus, we can understand that the LCM of 176,209,861,421 is 1212136464.
