Calculate the LCM of 561,563,408,551

Given numbers are 561,563,408,551

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

The LCM of 561,563,408,551 is 1392235944.

Find LCM of 561,563,408,551 with Prime Factorization


3 561, 563, 408, 551
17 187, 563, 136, 551
11, 563, 8, 551

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

3 x 17 x 11 x 563 x 8 x 551 = 1392235944

Therefore, the lowest common multiple of 561,563,408,551 is 1392235944.

LCM Formula to Find Lowest Common Multiple of 561,563,408,551

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.

561 x 563 x 408 x 551 = 71004033144

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

563 : 1, 563

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,563,408,551, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

563:563

408:2x 2x 2x 3x 17

551:19x 29

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

3x 17 = 51

Therefore, the value for common factors is 51.

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 = 71004033144/(1x51)

LCM = 71004033144/51

LCM = 1392235944

Thus, we can understand that the LCM of 561,563,408,551 is 1392235944.
