Calculate the LCM of 823,684,608,570

Given numbers are 823,684,608,570

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

The LCM of 823,684,608,570 is 22517280.

Find LCM of 823,684,608,570 with Prime Factorization


2 823, 684, 608, 570
2 823, 342, 304, 285
3 823, 171, 152, 285
19 823, 57, 152, 95
823, 3, 8, 5

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

2 x 2 x 3 x 19 x 823 x 3 x 8 x 5 = 22517280

Therefore, the lowest common multiple of 823,684,608,570 is 22517280.

LCM Formula to Find Lowest Common Multiple of 823,684,608,570

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.

823 x 684 x 608 x 570 = 195089713920

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.

823 : 1, 823

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,684,608,570, is 1.

Now, the common factors can be found like this.

823:823

684:2x 2x 3x 3x 19

608:2x 2x 2x 2x 2x 19

570:2x 3x 5x 19

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 2x 3x 19x 19 = 8664

Therefore, the value for common factors is 8664.

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 = 195089713920/(1x8664)

LCM = 195089713920/8664

LCM = 22517280

Thus, we can understand that the LCM of 823,684,608,570 is 22517280.
