Calculate the LCM of 589,728,491,688

Given numbers are 589,728,491,688

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

The LCM of 589,728,491,688 is 18106170992.

Find LCM of 589,728,491,688 with Prime Factorization


2 589, 728, 491, 688
2 589, 364, 491, 344
2 589, 182, 491, 172
589, 91, 491, 86

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

2 x 2 x 2 x 589 x 91 x 491 x 86 = 18106170992

Therefore, the lowest common multiple of 589,728,491,688 is 18106170992.

LCM Formula to Find Lowest Common Multiple of 589,728,491,688

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.

589 x 728 x 491 x 688 = 144849367936

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.

589 : 1, 19, 31, 589

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

491 : 1, 491

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 589,728,491,688, is 1.

Now, the common factors can be found like this.

589:19x 31

728:2x 2x 2x 7x 13

491:491

688:2x 2x 2x 2x 43

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 2 = 8

Therefore, the value for common factors is 8.

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 = 144849367936/(1x8)

LCM = 144849367936/8

LCM = 18106170992

Thus, we can understand that the LCM of 589,728,491,688 is 18106170992.
