Given numbers are 990,670,530,644

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

The LCM of 990,670,530,644 is 1131987780.

Find LCM of 990,670,530,644 with Prime Factorization

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

2 x 5 x 99 x 67 x 53 x 322 = 1131987780

Therefore, the lowest common multiple of 990,670,530,644 is 1131987780.

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.

990 x 670 x 530 x 644 = 226397556000

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

670 : 1, 2, 5, 10, 67, 134, 335, 670

530 : 1, 2, 5, 10, 53, 106, 265, 530

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,670,530,644, is 2.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

670:2x 5x 67

530:2x 5x 53

644:2x 2x 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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 226397556000/(2x100)

LCM = 226397556000/200

LCM = 1131987780

Thus, we can understand that the LCM of 990,670,530,644 is 1131987780.
