Given numbers are 791,817,129,890

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

The LCM of 791,817,129,890 is 1725479490.

Find LCM of 791,817,129,890 with Prime Factorization

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

43 x 791 x 19 x 3 x 890 = 1725479490

Therefore, the lowest common multiple of 791,817,129,890 is 1725479490.

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.

791 x 817 x 129 x 890 = 74195618070

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.

791 : 1, 7, 113, 791

817 : 1, 19, 43, 817

129 : 1, 3, 43, 129

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,817,129,890, is 1.

Now, the common factors can be found like this.

791:7x 113

817:19x 43

129:3x 43

890:2x 5x 89

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

43 = 43

Therefore, the value for common factors is 43.

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 = 74195618070/(1x43)

LCM = 74195618070/43

LCM = 1725479490

Thus, we can understand that the LCM of 791,817,129,890 is 1725479490.
