Given numbers are 770,643,167,668

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

The LCM of 770,643,167,668 is 165366740.

Find LCM of 770,643,167,668 with Prime Factorization

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

2 x 167 x 385 x 643 x 1 x 2 = 165366740

Therefore, the lowest common multiple of 770,643,167,668 is 165366740.

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.

770 x 643 x 167 x 668 = 55232491160

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

643 : 1, 643

167 : 1, 167

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,643,167,668, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

643:643

167:167

668:2x 2x 167

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

2x 167 = 334

Therefore, the value for common factors is 334.

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 = 55232491160/(1x334)

LCM = 55232491160/334

LCM = 165366740

Thus, we can understand that the LCM of 770,643,167,668 is 165366740.
