Given numbers are 530,578,617,642

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

The LCM of 530,578,617,642 is 30336390690.

Find LCM of 530,578,617,642 with Prime Factorization

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

2 x 265 x 289 x 617 x 321 = 30336390690

Therefore, the lowest common multiple of 530,578,617,642 is 30336390690.

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.

530 x 578 x 617 x 642 = 121345562760

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.

530 : 1, 2, 5, 10, 53, 106, 265, 530

578 : 1, 2, 17, 34, 289, 578

617 : 1, 617

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 530,578,617,642, is 1.

Now, the common factors can be found like this.

530:2x 5x 53

578:2x 17x 17

617:617

642:2x 3x 107

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 121345562760/(1x4)

LCM = 121345562760/4

LCM = 30336390690

Thus, we can understand that the LCM of 530,578,617,642 is 30336390690.
