Given numbers are 644,205,316,907

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

The LCM of 644,205,316,907 is 9459629060.

Find LCM of 644,205,316,907 with Prime Factorization

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

2 x 2 x 161 x 205 x 79 x 907 = 9459629060

Therefore, the lowest common multiple of 644,205,316,907 is 9459629060.

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 205 x 316 x 907 = 37838516240

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

205 : 1, 5, 41, 205

316 : 1, 2, 4, 79, 158, 316

907 : 1, 907

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,205,316,907, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

205:5x 41

316:2x 2x 79

907:907

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 37838516240/(1x4)

LCM = 37838516240/4

LCM = 9459629060

Thus, we can understand that the LCM of 644,205,316,907 is 9459629060.
