Given numbers are 639,431,345,759

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

The LCM of 639,431,345,759 is 348392385.

Find LCM of 639,431,345,759 with Prime Factorization

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

3 x 23 x 213 x 431 x 5 x 11 = 348392385

Therefore, the lowest common multiple of 639,431,345,759 is 348392385.

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.

639 x 431 x 345 x 759 = 72117223695

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.

639 : 1, 3, 9, 71, 213, 639

431 : 1, 431

345 : 1, 3, 5, 15, 23, 69, 115, 345

759 : 1, 3, 11, 23, 33, 69, 253, 759

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,431,345,759, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

431:431

345:3x 5x 23

759:3x 11x 23

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 23 = 207

Therefore, the value for common factors is 207.

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 = 72117223695/(1x207)

LCM = 72117223695/207

LCM = 348392385

Thus, we can understand that the LCM of 639,431,345,759 is 348392385.
