Calculate the LCM of 637,897,691,964

Given numbers are 637,897,691,964

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

The LCM of 637,897,691,964 is 29278148172.

Find LCM of 637,897,691,964 with Prime Factorization


13 637, 897, 691, 964
49, 69, 691, 964

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

13 x 49 x 69 x 691 x 964 = 29278148172

Therefore, the lowest common multiple of 637,897,691,964 is 29278148172.

LCM Formula to Find Lowest Common Multiple of 637,897,691,964

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.

637 x 897 x 691 x 964 = 380615926236

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.

637 : 1, 7, 13, 49, 91, 637

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

691 : 1, 691

964 : 1, 2, 4, 241, 482, 964

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,897,691,964, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

897:3x 13x 23

691:691

964:2x 2x 241

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

13 = 13

Therefore, the value for common factors is 13.

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 = 380615926236/(1x13)

LCM = 380615926236/13

LCM = 29278148172

Thus, we can understand that the LCM of 637,897,691,964 is 29278148172.
