Calculate the LCM of 990,668,598,166

Given numbers are 990,668,598,166

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

The LCM of 990,668,598,166 is 8205989220.

Find LCM of 990,668,598,166 with Prime Factorization


2 990, 668, 598, 166
495, 334, 299, 83

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

2 x 495 x 334 x 299 x 83 = 8205989220

Therefore, the lowest common multiple of 990,668,598,166 is 8205989220.

LCM Formula to Find Lowest Common Multiple of 990,668,598,166

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 668 x 598 x 166 = 65647913760

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

668 : 1, 2, 4, 167, 334, 668

598 : 1, 2, 13, 23, 26, 46, 299, 598

166 : 1, 2, 83, 166

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,668,598,166, is 2.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

668:2x 2x 167

598:2x 13x 23

166:2x 83

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 = 65647913760/(2x4)

LCM = 65647913760/8

LCM = 8205989220

Thus, we can understand that the LCM of 990,668,598,166 is 8205989220.
