Given numbers are 644,138,683,343

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

The LCM of 644,138,683,343 is 64658244.

Find LCM of 644,138,683,343 with Prime Factorization

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

2 x 7 x 23 x 2 x 3 x 683 x 49 = 64658244

Therefore, the lowest common multiple of 644,138,683,343 is 64658244.

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 138 x 683 x 343 = 20819954568

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

683 : 1, 683

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,138,683,343, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

138:2x 3x 23

683:683

343:7x 7x 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 7x 23 = 322

Therefore, the value for common factors is 322.

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 = 20819954568/(1x322)

LCM = 20819954568/322

LCM = 64658244

Thus, we can understand that the LCM of 644,138,683,343 is 64658244.
