Given numbers are 430,199,156,170

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

The LCM of 430,199,156,170 is 113465820.

Find LCM of 430,199,156,170 with Prime Factorization

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

2 x 5 x 43 x 199 x 78 x 17 = 113465820

Therefore, the lowest common multiple of 430,199,156,170 is 113465820.

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.

430 x 199 x 156 x 170 = 2269316400

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.

430 : 1, 2, 5, 10, 43, 86, 215, 430

199 : 1, 199

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

170 : 1, 2, 5, 10, 17, 34, 85, 170

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,199,156,170, is 1.

Now, the common factors can be found like this.

430:2x 5x 43

199:199

156:2x 2x 3x 13

170:2x 5x 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 5 = 20

Therefore, the value for common factors is 20.

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 = 2269316400/(1x20)

LCM = 2269316400/20

LCM = 113465820

Thus, we can understand that the LCM of 430,199,156,170 is 113465820.
