Given numbers are 620,298,780,450

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

The LCM of 620,298,780,450 is 54042300.

Find LCM of 620,298,780,450 with Prime Factorization

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

2 x 2 x 3 x 5 x 31 x 149 x 13 x 15 = 54042300

Therefore, the lowest common multiple of 620,298,780,450 is 54042300.

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 298 x 780 x 450 = 64850760000

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

298 : 1, 2, 149, 298

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

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,298,780,450, is 2.

Now, the common factors can be found like this.

620:2x 2x 5x 31

298:2x 149

780:2x 2x 3x 5x 13

450:2x 3x 3x 5x 5

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 3x 5x 5 = 600

Therefore, the value for common factors is 600.

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 = 64850760000/(2x600)

LCM = 64850760000/1200

LCM = 54042300

Thus, we can understand that the LCM of 620,298,780,450 is 54042300.
