Given numbers are 431,571,153,391

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

The LCM of 431,571,153,391 is 866029419.

Find LCM of 431,571,153,391 with Prime Factorization

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

17 x 431 x 571 x 9 x 23 = 866029419

Therefore, the lowest common multiple of 431,571,153,391 is 866029419.

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 571 x 153 x 391 = 14722500123

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

571 : 1, 571

153 : 1, 3, 9, 17, 51, 153

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,571,153,391, is 1.

Now, the common factors can be found like this.

431:431

571:571

153:3x 3x 17

391:17x 23

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

17 = 17

Therefore, the value for common factors is 17.

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 = 14722500123/(1x17)

LCM = 14722500123/17

LCM = 866029419

Thus, we can understand that the LCM of 431,571,153,391 is 866029419.
