Given numbers are 637,427,121

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

The LCM of 637,427,121 is 4701697.

Find LCM of 637,427,121 with Prime Factorization

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

7 x 91 x 61 x 121 = 4701697

Therefore, the lowest common multiple of 637,427,121 is 4701697.

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 427 x 121 = 32911879

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

427 : 1, 7, 61, 427

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,427,121, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

427:7x 61

121:11x 11

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

7 = 7

Therefore, the value for common factors is 7.

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 = 32911879/(1x7)

LCM = 32911879/7

LCM = 4701697

Thus, we can understand that the LCM of 637,427,121 is 4701697.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 726, 256, 609
• LCM of 205, 612, 986
