Calculate the LCM of 455,171,988,424

Given numbers are 455,171,988,424

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

The LCM of 455,171,988,424 is 32989320.

Find LCM of 455,171,988,424 with Prime Factorization


2 455, 171, 988, 424
2 455, 171, 494, 212
13 455, 171, 247, 106
19 35, 171, 19, 106
35, 9, 1, 106

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

2 x 2 x 13 x 19 x 35 x 9 x 1 x 106 = 32989320

Therefore, the lowest common multiple of 455,171,988,424 is 32989320.

LCM Formula to Find Lowest Common Multiple of 455,171,988,424

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.

455 x 171 x 988 x 424 = 32593448160

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

171 : 1, 3, 9, 19, 57, 171

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,171,988,424, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

171:3x 3x 19

988:2x 2x 13x 19

424:2x 2x 2x 53

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

2x 2x 13x 19 = 988

Therefore, the value for common factors is 988.

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 = 32593448160/(1x988)

LCM = 32593448160/988

LCM = 32989320

Thus, we can understand that the LCM of 455,171,988,424 is 32989320.
