Calculate the LCM of 431,273,535,809,428

Given numbers are 431,273,535,809,428

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

The LCM of 431,273,535,809,428 is 203705245380.

Find LCM of 431,273,535,809,428 with Prime Factorization


107 431, 273, 535, 809, 428
431, 273, 5, 809, 4

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

107 x 431 x 273 x 5 x 809 x 4 = 203705245380

Therefore, the lowest common multiple of 431,273,535,809,428 is 203705245380.

LCM Formula to Find Lowest Common Multiple of 431,273,535,809,428

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.

431 x 273 x 535 x 809 x 428 = 21796461255660

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.

431 : 1, 431

273 : 1, 3, 7, 13, 21, 39, 91, 273

535 : 1, 5, 107, 535

809 : 1, 809

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,273,535,809,428, is 1.

Now, the common factors can be found like this.

431:431

273:3x 7x 13

535:5x 107

809:809

428:2x 2x 107

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

107 = 107

Therefore, the value for common factors is 107.

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 = 21796461255660/(1x107)

LCM = 21796461255660/107

LCM = 203705245380

Thus, we can understand that the LCM of 431,273,535,809,428 is 203705245380.
