Given numbers are 254,165,680,169

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

The LCM of 254,165,680,169 is 481629720.

Find LCM of 254,165,680,169 with Prime Factorization

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

2 x 5 x 127 x 33 x 68 x 169 = 481629720

Therefore, the lowest common multiple of 254,165,680,169 is 481629720.

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.

254 x 165 x 680 x 169 = 4816297200

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.

254 : 1, 2, 127, 254

165 : 1, 3, 5, 11, 15, 33, 55, 165

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,165,680,169, is 1.

Now, the common factors can be found like this.

254:2x 127

165:3x 5x 11

680:2x 2x 2x 5x 17

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.

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 = 4816297200/(1x10)

LCM = 4816297200/10

LCM = 481629720

Thus, we can understand that the LCM of 254,165,680,169 is 481629720.
