Calculate the LCM of 897,672,437,321

Given numbers are 897,672,437,321

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

The LCM of 897,672,437,321 is 408486624.

Find LCM of 897,672,437,321 with Prime Factorization


3 897, 672, 437, 321
23 299, 224, 437, 107
13, 224, 19, 107

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

3 x 23 x 13 x 224 x 19 x 107 = 408486624

Therefore, the lowest common multiple of 897,672,437,321 is 408486624.

LCM Formula to Find Lowest Common Multiple of 897,672,437,321

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.

897 x 672 x 437 x 321 = 84556731168

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.

897 : 1, 3, 13, 23, 39, 69, 299, 897

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

437 : 1, 19, 23, 437

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,672,437,321, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

672:2x 2x 2x 2x 2x 3x 7

437:19x 23

321:3x 107

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

3x 3x 23 = 207

Therefore, the value for common factors is 207.

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 = 84556731168/(1x207)

LCM = 84556731168/207

LCM = 408486624

Thus, we can understand that the LCM of 897,672,437,321 is 408486624.
