Given numbers are 722,394,985,406

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

The LCM of 722,394,985,406 is 144367510.

Find LCM of 722,394,985,406 with Prime Factorization

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

2 x 197 x 361 x 1 x 5 x 203 = 144367510

Therefore, the lowest common multiple of 722,394,985,406 is 144367510.

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.

722 x 394 x 985 x 406 = 113761597880

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.

722 : 1, 2, 19, 38, 361, 722

394 : 1, 2, 197, 394

985 : 1, 5, 197, 985

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,394,985,406, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

394:2x 197

985:5x 197

406:2x 7x 29

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 197 = 788

Therefore, the value for common factors is 788.

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 = 113761597880/(1x788)

LCM = 113761597880/788

LCM = 144367510

Thus, we can understand that the LCM of 722,394,985,406 is 144367510.
