Given numbers are 722,523,643,644

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

The LCM of 722,523,643,644 is 78181811876.

Find LCM of 722,523,643,644 with Prime Factorization

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

2 x 361 x 523 x 643 x 322 = 78181811876

Therefore, the lowest common multiple of 722,523,643,644 is 78181811876.

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 523 x 643 x 644 = 156363623752

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

523 : 1, 523

643 : 1, 643

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,523,643,644, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

523:523

643:643

644:2x 2x 7x 23

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

2 = 2

Therefore, the value for common factors is 2.

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 = 156363623752/(1x2)

LCM = 156363623752/2

LCM = 78181811876

Thus, we can understand that the LCM of 722,523,643,644 is 78181811876.
