Given numbers are 461,621,805,620

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

The LCM of 461,621,805,620 is 1242459540.

Find LCM of 461,621,805,620 with Prime Factorization

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

5 x 23 x 461 x 27 x 7 x 124 = 1242459540

Therefore, the lowest common multiple of 461,621,805,620 is 1242459540.

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.

461 x 621 x 805 x 620 = 142882847100

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.

461 : 1, 461

621 : 1, 3, 9, 23, 27, 69, 207, 621

805 : 1, 5, 7, 23, 35, 115, 161, 805

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,621,805,620, is 1.

Now, the common factors can be found like this.

461:461

621:3x 3x 3x 23

805:5x 7x 23

620:2x 2x 5x 31

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

5x 23 = 115

Therefore, the value for common factors is 115.

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 = 142882847100/(1x115)

LCM = 142882847100/115

LCM = 1242459540

Thus, we can understand that the LCM of 461,621,805,620 is 1242459540.
