Calculate the LCM of 574,399,440,649

Given numbers are 574,399,440,649

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

The LCM of 574,399,440,649 is 424679640.

Find LCM of 574,399,440,649 with Prime Factorization


2 574, 399, 440, 649
7 287, 399, 220, 649
11 41, 57, 220, 649
41, 57, 20, 59

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

2 x 7 x 11 x 41 x 57 x 20 x 59 = 424679640

Therefore, the lowest common multiple of 574,399,440,649 is 424679640.

LCM Formula to Find Lowest Common Multiple of 574,399,440,649

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.

574 x 399 x 440 x 649 = 65400664560

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.

574 : 1, 2, 7, 14, 41, 82, 287, 574

399 : 1, 3, 7, 19, 21, 57, 133, 399

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

649 : 1, 11, 59, 649

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 574,399,440,649, is 1.

Now, the common factors can be found like this.

574:2x 7x 41

399:3x 7x 19

440:2x 2x 2x 5x 11

649:11x 59

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

2x 7x 11 = 154

Therefore, the value for common factors is 154.

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 = 65400664560/(1x154)

LCM = 65400664560/154

LCM = 424679640

Thus, we can understand that the LCM of 574,399,440,649 is 424679640.
