Given numbers are 821,554,175,460

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

The LCM of 821,554,175,460 is 3661413700.

Find LCM of 821,554,175,460 with Prime Factorization

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

2 x 5 x 821 x 277 x 35 x 46 = 3661413700

Therefore, the lowest common multiple of 821,554,175,460 is 3661413700.

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.

821 x 554 x 175 x 460 = 36614137000

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.

821 : 1, 821

554 : 1, 2, 277, 554

175 : 1, 5, 7, 25, 35, 175

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,554,175,460, is 1.

Now, the common factors can be found like this.

821:821

554:2x 277

175:5x 5x 7

460:2x 2x 5x 23

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 = 36614137000/(1x10)

LCM = 36614137000/10

LCM = 3661413700

Thus, we can understand that the LCM of 821,554,175,460 is 3661413700.
