Given numbers are 197,620,789,730

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

The LCM of 197,620,789,730 is 7034897580.

Find LCM of 197,620,789,730 with Prime Factorization

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

2 x 5 x 197 x 62 x 789 x 73 = 7034897580

Therefore, the lowest common multiple of 197,620,789,730 is 7034897580.

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.

197 x 620 x 789 x 730 = 70348975800

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.

197 : 1, 197

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

789 : 1, 3, 263, 789

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,620,789,730, is 1.

Now, the common factors can be found like this.

197:197

620:2x 2x 5x 31

789:3x 263

730:2x 5x 73

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 70348975800/(1x10)

LCM = 70348975800/10

LCM = 7034897580

Thus, we can understand that the LCM of 197,620,789,730 is 7034897580.
