Calculate the LCM of 457,771,585,817,458

Given numbers are 457,771,585,817,458

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

The LCM of 457,771,585,817,458 is 25709446335690.

Find LCM of 457,771,585,817,458 with Prime Factorization


3 457, 771, 585, 817, 458
457, 257, 195, 817, 458

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

3 x 457 x 257 x 195 x 817 x 458 = 25709446335690

Therefore, the lowest common multiple of 457,771,585,817,458 is 25709446335690.

LCM Formula to Find Lowest Common Multiple of 457,771,585,817,458

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.

457 x 771 x 585 x 817 x 458 = 77128339007070

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.

457 : 1, 457

771 : 1, 3, 257, 771

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

817 : 1, 19, 43, 817

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,771,585,817,458, is 1.

Now, the common factors can be found like this.

457:457

771:3x 257

585:3x 3x 5x 13

817:19x 43

458:2x 229

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

3 = 3

Therefore, the value for common factors is 3.

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 = 77128339007070/(1x3)

LCM = 77128339007070/3

LCM = 25709446335690

Thus, we can understand that the LCM of 457,771,585,817,458 is 25709446335690.
