Given numbers are 506,420,520,610,545

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

The LCM of 506,420,520,610,545 is 18369591240.

Find LCM of 506,420,520,610,545 with Prime Factorization

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

2 x 2 x 5 x 253 x 21 x 26 x 61 x 109 = 18369591240

Therefore, the lowest common multiple of 506,420,520,610,545 is 18369591240.

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.

506 x 420 x 520 x 610 x 545 = 36739182480000

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.

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

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

610 : 1, 2, 5, 10, 61, 122, 305, 610

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 506,420,520,610,545, is 1.

Now, the common factors can be found like this.

506:2x 11x 23

420:2x 2x 3x 5x 7

520:2x 2x 2x 5x 13

610:2x 5x 61

545:5x 109

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 2x 5x 5x 5 = 2000

Therefore, the value for common factors is 2000.

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 = 36739182480000/(1x2000)

LCM = 36739182480000/2000

LCM = 18369591240

Thus, we can understand that the LCM of 506,420,520,610,545 is 18369591240.
