Given numbers are 397,653,653,661

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

The LCM of 397,653,653,661 is 171358301.

Find LCM of 397,653,653,661 with Prime Factorization

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

653 x 397 x 1 x 1 x 661 = 171358301

Therefore, the lowest common multiple of 397,653,653,661 is 171358301.

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.

397 x 653 x 653 x 661 = 111896970553

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.

397 : 1, 397

653 : 1, 653

653 : 1, 653

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,653,653,661, is 1.

Now, the common factors can be found like this.

397:397

653:653

653:653

661:661

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

653 = 653

Therefore, the value for common factors is 653.

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 = 111896970553/(1x653)

LCM = 111896970553/653

LCM = 171358301

Thus, we can understand that the LCM of 397,653,653,661 is 171358301.

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