Given numbers are 802,382,181,420

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

The LCM of 802,382,181,420 is 5822447820.

Find LCM of 802,382,181,420 with Prime Factorization

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

2 x 401 x 191 x 181 x 210 = 5822447820

Therefore, the lowest common multiple of 802,382,181,420 is 5822447820.

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 382 x 181 x 420 = 23289791280

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

382 : 1, 2, 191, 382

181 : 1, 181

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,382,181,420, is 1.

Now, the common factors can be found like this.

802:2x 401

382:2x 191

181:181

420:2x 2x 3x 5x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 23289791280/(1x4)

LCM = 23289791280/4

LCM = 5822447820

Thus, we can understand that the LCM of 802,382,181,420 is 5822447820.
