Calculate the LCM of 810,890,140,341

Given numbers are 810,890,140,341

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

The LCM of 810,890,140,341 is 344157660.

Find LCM of 810,890,140,341 with Prime Factorization


2 810, 890, 140, 341
5 405, 445, 70, 341
81, 89, 14, 341

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

2 x 5 x 81 x 89 x 14 x 341 = 344157660

Therefore, the lowest common multiple of 810,890,140,341 is 344157660.

LCM Formula to Find Lowest Common Multiple of 810,890,140,341

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.

810 x 890 x 140 x 341 = 34415766000

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

890 : 1, 2, 5, 10, 89, 178, 445, 890

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

341 : 1, 11, 31, 341

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,890,140,341, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

890:2x 5x 89

140:2x 2x 5x 7

341:11x 31

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 = 34415766000/(1x100)

LCM = 34415766000/100

LCM = 344157660

Thus, we can understand that the LCM of 810,890,140,341 is 344157660.
