Given numbers are 174,197,406,689

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

The LCM of 174,197,406,689 is 165322794.

Find LCM of 174,197,406,689 with Prime Factorization

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

2 x 29 x 3 x 197 x 7 x 689 = 165322794

Therefore, the lowest common multiple of 174,197,406,689 is 165322794.

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.

174 x 197 x 406 x 689 = 9588722052

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.

174 : 1, 2, 3, 6, 29, 58, 87, 174

197 : 1, 197

406 : 1, 2, 7, 14, 29, 58, 203, 406

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,197,406,689, is 1.

Now, the common factors can be found like this.

174:2x 3x 29

197:197

406:2x 7x 29

689:13x 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 29 = 58

Therefore, the value for common factors is 58.

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 = 9588722052/(1x58)

LCM = 9588722052/58

LCM = 165322794

Thus, we can understand that the LCM of 174,197,406,689 is 165322794.
