Given numbers are 802,641,394,401,280

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

The LCM of 802,641,394,401,280 is 14178381560.

Find LCM of 802,641,394,401,280 with Prime Factorization

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

2 x 401 x 1 x 641 x 197 x 1 x 140 = 14178381560

Therefore, the lowest common multiple of 802,641,394,401,280 is 14178381560.

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 641 x 394 x 401 x 280 = 22742124022240

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

641 : 1, 641

394 : 1, 2, 197, 394

401 : 1, 401

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,641,394,401,280, is 1.

Now, the common factors can be found like this.

802:2x 401

641:641

394:2x 197

401:401

280:2x 2x 2x 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 2x 401 = 1604

Therefore, the value for common factors is 1604.

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 = 22742124022240/(1x1604)

LCM = 22742124022240/1604

LCM = 14178381560

Thus, we can understand that the LCM of 802,641,394,401,280 is 14178381560.
