Given numbers are 471,561,391,357

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

The LCM of 471,561,391,357 is 14180397.

Find LCM of 471,561,391,357 with Prime Factorization

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

3 x 17 x 157 x 11 x 23 x 7 = 14180397

Therefore, the lowest common multiple of 471,561,391,357 is 14180397.

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.

471 x 561 x 391 x 357 = 36883212597

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.

471 : 1, 3, 157, 471

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

391 : 1, 17, 23, 391

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,561,391,357, is 1.

Now, the common factors can be found like this.

471:3x 157

561:3x 11x 17

391:17x 23

357:3x 7x 17

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

3x 3x 17x 17 = 2601

Therefore, the value for common factors is 2601.

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 = 36883212597/(1x2601)

LCM = 36883212597/2601

LCM = 14180397

Thus, we can understand that the LCM of 471,561,391,357 is 14180397.
