Calculate the LCM of 170,850,990,850

Given numbers are 170,850,990,850

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

The LCM of 170,850,990,850 is 84150.

Find LCM of 170,850,990,850 with Prime Factorization


2 170, 850, 990, 850
5 85, 425, 495, 425
5 17, 85, 99, 85
17 17, 17, 99, 17
1, 1, 99, 1

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

2 x 5 x 5 x 17 x 1 x 1 x 99 x 1 = 84150

Therefore, the lowest common multiple of 170,850,990,850 is 84150.

LCM Formula to Find Lowest Common Multiple of 170,850,990,850

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.

170 x 850 x 990 x 850 = 121596750000

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.

170 : 1, 2, 5, 10, 17, 34, 85, 170

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

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

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

10 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,850,990,850, is 10.

Now, the common factors can be found like this.

170:2x 5x 17

850:2x 5x 5x 17

990:2x 3x 3x 5x 11

850:2x 5x 5x 17

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 5x 5x 17x 17 = 144500

Therefore, the value for common factors is 144500.

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 = 121596750000/(10x144500)

LCM = 121596750000/1445000

LCM = 84150

Thus, we can understand that the LCM of 170,850,990,850 is 84150.
