Given numbers are 345,539,473,142,781

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

The LCM of 345,539,473,142,781 is 1135441230.

Find LCM of 345,539,473,142,781 with Prime Factorization

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

11 x 71 x 345 x 49 x 43 x 2 x 1 = 1135441230

Therefore, the lowest common multiple of 345,539,473,142,781 is 1135441230.

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 539 x 473 x 142 x 781 = 9754575606930

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

539 : 1, 7, 11, 49, 77, 539

473 : 1, 11, 43, 473

142 : 1, 2, 71, 142

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,539,473,142,781, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

539:7x 7x 11

473:11x 43

142:2x 71

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.

11x 11x 71 = 8591

Therefore, the value for common factors is 8591.

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 = 9754575606930/(1x8591)

LCM = 9754575606930/8591

LCM = 1135441230

Thus, we can understand that the LCM of 345,539,473,142,781 is 1135441230.
