Given numbers are 842,781,136,531

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

The LCM of 842,781,136,531 is 23744693016.

Find LCM of 842,781,136,531 with Prime Factorization

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

2 x 421 x 781 x 68 x 531 = 23744693016

Therefore, the lowest common multiple of 842,781,136,531 is 23744693016.

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.

842 x 781 x 136 x 531 = 47489386032

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.

842 : 1, 2, 421, 842

781 : 1, 11, 71, 781

136 : 1, 2, 4, 8, 17, 34, 68, 136

531 : 1, 3, 9, 59, 177, 531

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,781,136,531, is 1.

Now, the common factors can be found like this.

842:2x 421

781:11x 71

136:2x 2x 2x 17

531:3x 3x 59

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

2 = 2

Therefore, the value for common factors is 2.

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 = 47489386032/(1x2)

LCM = 47489386032/2

LCM = 23744693016

Thus, we can understand that the LCM of 842,781,136,531 is 23744693016.
