Given numbers are 644,713,943,669

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

The LCM of 644,713,943,669 is 547592556.

Find LCM of 644,713,943,669 with Prime Factorization

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

23 x 28 x 31 x 41 x 669 = 547592556

Therefore, the lowest common multiple of 644,713,943,669 is 547592556.

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.

644 x 713 x 943 x 669 = 289676462124

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.

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

713 : 1, 23, 31, 713

943 : 1, 23, 41, 943

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,713,943,669, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

713:23x 31

943:23x 41

669:3x 223

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 289676462124/(1x529)

LCM = 289676462124/529

LCM = 547592556

Thus, we can understand that the LCM of 644,713,943,669 is 547592556.
