Given numbers are 257,134,680,136

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

The LCM of 257,134,680,136 is 11708920.

Find LCM of 257,134,680,136 with Prime Factorization

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

2 x 2 x 2 x 17 x 257 x 67 x 5 x 1 = 11708920

Therefore, the lowest common multiple of 257,134,680,136 is 11708920.

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.

257 x 134 x 680 x 136 = 3184826240

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.

257 : 1, 257

134 : 1, 2, 67, 134

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

136 : 1, 2, 4, 8, 17, 34, 68, 136

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,134,680,136, is 1.

Now, the common factors can be found like this.

257:257

134:2x 67

680:2x 2x 2x 5x 17

136:2x 2x 2x 17

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

2x 2x 2x 2x 17 = 272

Therefore, the value for common factors is 272.

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 = 3184826240/(1x272)

LCM = 3184826240/272

LCM = 11708920

Thus, we can understand that the LCM of 257,134,680,136 is 11708920.
