Given numbers are 743,642,322,528,397

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

The LCM of 743,642,322,528,397 is 2683013740176.

Find LCM of 743,642,322,528,397 with Prime Factorization

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

2 x 3 x 743 x 107 x 161 x 88 x 397 = 2683013740176

Therefore, the lowest common multiple of 743,642,322,528,397 is 2683013740176.

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.

743 x 642 x 322 x 528 x 397 = 32196164882112

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.

743 : 1, 743

642 : 1, 2, 3, 6, 107, 214, 321, 642

322 : 1, 2, 7, 14, 23, 46, 161, 322

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,642,322,528,397, is 1.

Now, the common factors can be found like this.

743:743

642:2x 3x 107

322:2x 7x 23

528:2x 2x 2x 2x 3x 11

397:397

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 3 = 12

Therefore, the value for common factors is 12.

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 = 32196164882112/(1x12)

LCM = 32196164882112/12

LCM = 2683013740176

Thus, we can understand that the LCM of 743,642,322,528,397 is 2683013740176.
