Given numbers are 207,197,186,168

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

The LCM of 207,197,186,168 is 70792344.

Find LCM of 207,197,186,168 with Prime Factorization

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

2 x 3 x 69 x 197 x 31 x 28 = 70792344

Therefore, the lowest common multiple of 207,197,186,168 is 70792344.

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.

207 x 197 x 186 x 168 = 1274262192

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.

207 : 1, 3, 9, 23, 69, 207

197 : 1, 197

186 : 1, 2, 3, 6, 31, 62, 93, 186

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,197,186,168, is 1.

Now, the common factors can be found like this.

207:3x 3x 23

197:197

186:2x 3x 31

168:2x 2x 2x 3x 7

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 1274262192/(1x18)

LCM = 1274262192/18

LCM = 70792344

Thus, we can understand that the LCM of 207,197,186,168 is 70792344.
