Given numbers are 655,689,169,169

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

The LCM of 655,689,169,169 is 5866835.

Find LCM of 655,689,169,169 with Prime Factorization

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

13 x 13 x 655 x 53 x 1 x 1 = 5866835

Therefore, the lowest common multiple of 655,689,169,169 is 5866835.

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.

655 x 689 x 169 x 169 = 12889436495

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.

655 : 1, 5, 131, 655

689 : 1, 13, 53, 689

169 : 1, 13, 169

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,689,169,169, is 1.

Now, the common factors can be found like this.

655:5x 131

689:13x 53

169:13x 13

169:13x 13

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

13x 13x 13 = 2197

Therefore, the value for common factors is 2197.

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 = 12889436495/(1x2197)

LCM = 12889436495/2197

LCM = 5866835

Thus, we can understand that the LCM of 655,689,169,169 is 5866835.
