Calculate the LCM of 209,756,817,731

Given numbers are 209,756,817,731

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

The LCM of 209,756,817,731 is 115500924.

Find LCM of 209,756,817,731 with Prime Factorization


19 209, 756, 817, 731
43 11, 756, 43, 731
11, 756, 1, 17

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

19 x 43 x 11 x 756 x 1 x 17 = 115500924

Therefore, the lowest common multiple of 209,756,817,731 is 115500924.

LCM Formula to Find Lowest Common Multiple of 209,756,817,731

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.

209 x 756 x 817 x 731 = 94364254908

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.

209 : 1, 11, 19, 209

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

817 : 1, 19, 43, 817

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,756,817,731, is 1.

Now, the common factors can be found like this.

209:11x 19

756:2x 2x 3x 3x 3x 7

817:19x 43

731:17x 43

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

19x 43 = 817

Therefore, the value for common factors is 817.

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 = 94364254908/(1x817)

LCM = 94364254908/817

LCM = 115500924

Thus, we can understand that the LCM of 209,756,817,731 is 115500924.
