Given numbers are 170,188,451,942

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

The LCM of 170,188,451,942 is 3394487580.

Find LCM of 170,188,451,942 with Prime Factorization

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

2 x 85 x 94 x 451 x 471 = 3394487580

Therefore, the lowest common multiple of 170,188,451,942 is 3394487580.

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.

170 x 188 x 451 x 942 = 13577950320

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.

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

188 : 1, 2, 4, 47, 94, 188

451 : 1, 11, 41, 451

942 : 1, 2, 3, 6, 157, 314, 471, 942

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,188,451,942, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

188:2x 2x 47

451:11x 41

942:2x 3x 157

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 13577950320/(1x4)

LCM = 13577950320/4

LCM = 3394487580

Thus, we can understand that the LCM of 170,188,451,942 is 3394487580.
