Given numbers are 431,209,154,475

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

The LCM of 431,209,154,475 is 31527650.

Find LCM of 431,209,154,475 with Prime Factorization

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

11 x 19 x 431 x 1 x 14 x 25 = 31527650

Therefore, the lowest common multiple of 431,209,154,475 is 31527650.

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.

431 x 209 x 154 x 475 = 6589278850

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.

431 : 1, 431

209 : 1, 11, 19, 209

154 : 1, 2, 7, 11, 14, 22, 77, 154

475 : 1, 5, 19, 25, 95, 475

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,209,154,475, is 1.

Now, the common factors can be found like this.

431:431

209:11x 19

154:2x 7x 11

475:5x 5x 19

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 6589278850/(1x209)

LCM = 6589278850/209

LCM = 31527650

Thus, we can understand that the LCM of 431,209,154,475 is 31527650.
