Given numbers are 784,942,810,531

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

The LCM of 784,942,810,531 is 2941187760.

Find LCM of 784,942,810,531 with Prime Factorization

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

2 x 3 x 3 x 392 x 157 x 45 x 59 = 2941187760

Therefore, the lowest common multiple of 784,942,810,531 is 2941187760.

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.

784 x 942 x 810 x 531 = 317648278080

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.

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

942 : 1, 2, 3, 6, 157, 314, 471, 942

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

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 784,942,810,531, is 1.

Now, the common factors can be found like this.

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

942:2x 3x 157

810:2x 3x 3x 3x 3x 5

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.

2x 2x 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 317648278080/(1x108)

LCM = 317648278080/108

LCM = 2941187760

Thus, we can understand that the LCM of 784,942,810,531 is 2941187760.
