Given numbers are 809,850,420,143

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

The LCM of 809,850,420,143 is 4130025900.

Find LCM of 809,850,420,143 with Prime Factorization

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

2 x 5 x 809 x 85 x 42 x 143 = 4130025900

Therefore, the lowest common multiple of 809,850,420,143 is 4130025900.

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.

809 x 850 x 420 x 143 = 41300259000

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.

809 : 1, 809

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,850,420,143, is 1.

Now, the common factors can be found like this.

809:809

850:2x 5x 5x 17

420:2x 2x 3x 5x 7

143:11x 13

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 = 41300259000/(1x10)

LCM = 41300259000/10

LCM = 4130025900

Thus, we can understand that the LCM of 809,850,420,143 is 4130025900.
