Given numbers are 810,820,254,661

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

The LCM of 810,820,254,661 is 5575759740.

Find LCM of 810,820,254,661 with Prime Factorization

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

2 x 5 x 81 x 82 x 127 x 661 = 5575759740

Therefore, the lowest common multiple of 810,820,254,661 is 5575759740.

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.

810 x 820 x 254 x 661 = 111515194800

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.

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

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

254 : 1, 2, 127, 254

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,820,254,661, is 1.

Now, the common factors can be found like this.

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

820:2x 2x 5x 41

254:2x 127

661:661

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 5 = 20

Therefore, the value for common factors is 20.

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 = 111515194800/(1x20)

LCM = 111515194800/20

LCM = 5575759740

Thus, we can understand that the LCM of 810,820,254,661 is 5575759740.
