Given numbers are 644,372,313,764

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

The LCM of 644,372,313,764 is 3580523436.

Find LCM of 644,372,313,764 with Prime Factorization

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

2 x 2 x 161 x 93 x 313 x 191 = 3580523436

Therefore, the lowest common multiple of 644,372,313,764 is 3580523436.

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 372 x 313 x 764 = 57288374976

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

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

313 : 1, 313

764 : 1, 2, 4, 191, 382, 764

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,372,313,764, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

372:2x 2x 3x 31

313:313

764:2x 2x 191

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 57288374976/(1x16)

LCM = 57288374976/16

LCM = 3580523436

Thus, we can understand that the LCM of 644,372,313,764 is 3580523436.
