Given numbers are 345,426,291,781

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

The LCM of 345,426,291,781 is 52272330.

Find LCM of 345,426,291,781 with Prime Factorization

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

3 x 71 x 115 x 2 x 97 x 11 = 52272330

Therefore, the lowest common multiple of 345,426,291,781 is 52272330.

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.

345 x 426 x 291 x 781 = 33402018870

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.

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

426 : 1, 2, 3, 6, 71, 142, 213, 426

291 : 1, 3, 97, 291

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,426,291,781, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

426:2x 3x 71

291:3x 97

781:11x 71

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 71 = 639

Therefore, the value for common factors is 639.

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 = 33402018870/(1x639)

LCM = 33402018870/639

LCM = 52272330

Thus, we can understand that the LCM of 345,426,291,781 is 52272330.
