Given numbers are 664,767,747,170

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

The LCM of 664,767,747,170 is 389605320.

Find LCM of 664,767,747,170 with Prime Factorization

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

2 x 83 x 4 x 767 x 9 x 85 = 389605320

Therefore, the lowest common multiple of 664,767,747,170 is 389605320.

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.

664 x 767 x 747 x 170 = 64674483120

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

767 : 1, 13, 59, 767

747 : 1, 3, 9, 83, 249, 747

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 664,767,747,170, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

767:13x 59

747:3x 3x 83

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 83 = 166

Therefore, the value for common factors is 166.

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 = 64674483120/(1x166)

LCM = 64674483120/166

LCM = 389605320

Thus, we can understand that the LCM of 664,767,747,170 is 389605320.
