Given numbers are 197,610,427,688

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

The LCM of 197,610,427,688 is 289369360.

Find LCM of 197,610,427,688 with Prime Factorization

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

2 x 61 x 197 x 5 x 7 x 344 = 289369360

Therefore, the lowest common multiple of 197,610,427,688 is 289369360.

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 610 x 427 x 688 = 35303061920

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

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

427 : 1, 7, 61, 427

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,610,427,688, is 1.

Now, the common factors can be found like this.

197:197

610:2x 5x 61

427:7x 61

688:2x 2x 2x 2x 43

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

2x 61 = 122

Therefore, the value for common factors is 122.

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 = 35303061920/(1x122)

LCM = 35303061920/122

LCM = 289369360

Thus, we can understand that the LCM of 197,610,427,688 is 289369360.
