Given numbers are 644,571,908,547

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

The LCM of 644,571,908,547 is 45659921356.

Find LCM of 644,571,908,547 with Prime Factorization

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

2 x 2 x 161 x 571 x 227 x 547 = 45659921356

Therefore, the lowest common multiple of 644,571,908,547 is 45659921356.

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 571 x 908 x 547 = 182639685424

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

571 : 1, 571

908 : 1, 2, 4, 227, 454, 908

547 : 1, 547

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,571,908,547, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

571:571

908:2x 2x 227

547:547

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 = 182639685424/(1x4)

LCM = 182639685424/4

LCM = 45659921356

Thus, we can understand that the LCM of 644,571,908,547 is 45659921356.
