Given numbers are 842,138,542,784

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

The LCM of 842,138,542,784 is 6171866736.

Find LCM of 842,138,542,784 with Prime Factorization

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

2 x 421 x 69 x 271 x 392 = 6171866736

Therefore, the lowest common multiple of 842,138,542,784 is 6171866736.

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 138 x 542 x 784 = 49374933888

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

542 : 1, 2, 271, 542

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,138,542,784, is 2.

Now, the common factors can be found like this.

842:2x 421

138:2x 3x 23

542:2x 271

784:2x 2x 2x 2x 7x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 49374933888/(2x4)

LCM = 49374933888/8

LCM = 6171866736

Thus, we can understand that the LCM of 842,138,542,784 is 6171866736.
