Given numbers are 644,630,994,483

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

The LCM of 644,630,994,483 is 2057580.

Find LCM of 644,630,994,483 with Prime Factorization

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

2 x 3 x 7 x 23 x 2 x 15 x 71 x 1 = 2057580

Therefore, the lowest common multiple of 644,630,994,483 is 2057580.

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 630 x 994 x 483 = 194786983440

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

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

994 : 1, 2, 7, 14, 71, 142, 497, 994

483 : 1, 3, 7, 21, 23, 69, 161, 483

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,630,994,483, is 7.

Now, the common factors can be found like this.

644:2x 2x 7x 23

630:2x 3x 3x 5x 7

994:2x 7x 71

483:3x 7x 23

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 3x 7x 7x 23 = 13524

Therefore, the value for common factors is 13524.

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 = 194786983440/(7x13524)

LCM = 194786983440/94668

LCM = 2057580

Thus, we can understand that the LCM of 644,630,994,483 is 2057580.
