Given numbers are 655,194,790,821

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

The LCM of 655,194,790,821 is 8241633130.

Find LCM of 655,194,790,821 with Prime Factorization

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

2 x 5 x 131 x 97 x 79 x 821 = 8241633130

Therefore, the lowest common multiple of 655,194,790,821 is 8241633130.

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.

655 x 194 x 790 x 821 = 82416331300

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.

655 : 1, 5, 131, 655

194 : 1, 2, 97, 194

790 : 1, 2, 5, 10, 79, 158, 395, 790

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,194,790,821, is 1.

Now, the common factors can be found like this.

655:5x 131

194:2x 97

790:2x 5x 79

821:821

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 82416331300/(1x10)

LCM = 82416331300/10

LCM = 8241633130

Thus, we can understand that the LCM of 655,194,790,821 is 8241633130.
