Given numbers are 387,953,740,170

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

The LCM of 387,953,740,170 is 4639642380.

Find LCM of 387,953,740,170 with Prime Factorization

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

2 x 5 x 387 x 953 x 74 x 17 = 4639642380

Therefore, the lowest common multiple of 387,953,740,170 is 4639642380.

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.

387 x 953 x 740 x 170 = 46396423800

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.

387 : 1, 3, 9, 43, 129, 387

953 : 1, 953

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

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 387,953,740,170, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

953:953

740:2x 2x 5x 37

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 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 = 46396423800/(1x10)

LCM = 46396423800/10

LCM = 4639642380

Thus, we can understand that the LCM of 387,953,740,170 is 4639642380.
