Given numbers are 620,190,805,329,742

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

The LCM of 620,190,805,329,742 is 4724380780.

Find LCM of 620,190,805,329,742 with Prime Factorization

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

2 x 5 x 7 x 62 x 19 x 23 x 47 x 53 = 4724380780

Therefore, the lowest common multiple of 620,190,805,329,742 is 4724380780.

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.

620 x 190 x 805 x 329 x 742 = 23149465822000

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

190 : 1, 2, 5, 10, 19, 38, 95, 190

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

329 : 1, 7, 47, 329

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,190,805,329,742, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

190:2x 5x 19

805:5x 7x 23

329:7x 47

742:2x 7x 53

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 5x 7x 7 = 4900

Therefore, the value for common factors is 4900.

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 = 23149465822000/(1x4900)

LCM = 23149465822000/4900

LCM = 4724380780

Thus, we can understand that the LCM of 620,190,805,329,742 is 4724380780.
