Given numbers are 997,802,351,221

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

The LCM of 997,802,351,221 is 4771177398.

Find LCM of 997,802,351,221 with Prime Factorization

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

13 x 997 x 802 x 27 x 17 = 4771177398

Therefore, the lowest common multiple of 997,802,351,221 is 4771177398.

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.

997 x 802 x 351 x 221 = 62025306174

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.

997 : 1, 997

802 : 1, 2, 401, 802

351 : 1, 3, 9, 13, 27, 39, 117, 351

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,802,351,221, is 1.

Now, the common factors can be found like this.

997:997

802:2x 401

351:3x 3x 3x 13

221:13x 17

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 = 62025306174/(1x13)

LCM = 62025306174/13

LCM = 4771177398

Thus, we can understand that the LCM of 997,802,351,221 is 4771177398.
