Calculate the LCM of 585,506,790,728

Given numbers are 585,506,790,728

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

The LCM of 585,506,790,728 is 654774120.

Find LCM of 585,506,790,728 with Prime Factorization


2 585, 506, 790, 728
5 585, 253, 395, 364
13 117, 253, 79, 364
9, 253, 79, 28

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

2 x 5 x 13 x 9 x 253 x 79 x 28 = 654774120

Therefore, the lowest common multiple of 585,506,790,728 is 654774120.

LCM Formula to Find Lowest Common Multiple of 585,506,790,728

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.

585 x 506 x 790 x 728 = 170241271200

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.

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

506 : 1, 2, 11, 22, 23, 46, 253, 506

790 : 1, 2, 5, 10, 79, 158, 395, 790

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 585,506,790,728, is 1.

Now, the common factors can be found like this.

585:3x 3x 5x 13

506:2x 11x 23

790:2x 5x 79

728:2x 2x 2x 7x 13

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 13 = 260

Therefore, the value for common factors is 260.

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 = 170241271200/(1x260)

LCM = 170241271200/260

LCM = 654774120

Thus, we can understand that the LCM of 585,506,790,728 is 654774120.
