Given numbers are 802,427,401,639

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

The LCM of 802,427,401,639 is 218828106.

Find LCM of 802,427,401,639 with Prime Factorization

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

401 x 2 x 427 x 1 x 639 = 218828106

Therefore, the lowest common multiple of 802,427,401,639 is 218828106.

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.

802 x 427 x 401 x 639 = 87750070506

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.

802 : 1, 2, 401, 802

427 : 1, 7, 61, 427

401 : 1, 401

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,427,401,639, is 1.

Now, the common factors can be found like this.

802:2x 401

427:7x 61

401:401

639:3x 3x 71

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

401 = 401

Therefore, the value for common factors is 401.

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 = 87750070506/(1x401)

LCM = 87750070506/401

LCM = 218828106

Thus, we can understand that the LCM of 802,427,401,639 is 218828106.
