Given numbers are 517,690,805,522,780

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

The LCM of 517,690,805,522,780 is 5648462820.

Find LCM of 517,690,805,522,780 with Prime Factorization

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

2 x 3 x 5 x 23 x 517 x 1 x 7 x 87 x 26 = 5648462820

Therefore, the lowest common multiple of 517,690,805,522,780 is 5648462820.

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.

517 x 690 x 805 x 522 x 780 = 116923180374000

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.

517 : 1, 11, 47, 517

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

805 : 1, 5, 7, 23, 35, 115, 161, 805

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,690,805,522,780, is 1.

Now, the common factors can be found like this.

517:11x 47

690:2x 3x 5x 23

805:5x 7x 23

522:2x 3x 3x 29

780:2x 2x 3x 5x 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 3x 3x 5x 5x 23 = 20700

Therefore, the value for common factors is 20700.

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 = 116923180374000/(1x20700)

LCM = 116923180374000/20700

LCM = 5648462820

Thus, we can understand that the LCM of 517,690,805,522,780 is 5648462820.
