Given numbers are 157,473,231,431

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

The LCM of 157,473,231,431 is 672136311.

Find LCM of 157,473,231,431 with Prime Factorization

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

11 x 157 x 43 x 21 x 431 = 672136311

Therefore, the lowest common multiple of 157,473,231,431 is 672136311.

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.

157 x 473 x 231 x 431 = 7393499421

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.

157 : 1, 157

473 : 1, 11, 43, 473

231 : 1, 3, 7, 11, 21, 33, 77, 231

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,473,231,431, is 1.

Now, the common factors can be found like this.

157:157

473:11x 43

231:3x 7x 11

431:431

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 = 7393499421/(1x11)

LCM = 7393499421/11

LCM = 672136311

Thus, we can understand that the LCM of 157,473,231,431 is 672136311.
