Given numbers are 767,668,455,121

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

The LCM of 767,668,455,121 is 2169827660.

Find LCM of 767,668,455,121 with Prime Factorization

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

13 x 59 x 668 x 35 x 121 = 2169827660

Therefore, the lowest common multiple of 767,668,455,121 is 2169827660.

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.

767 x 668 x 455 x 121 = 28207759580

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.

767 : 1, 13, 59, 767

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

455 : 1, 5, 7, 13, 35, 65, 91, 455

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,668,455,121, is 1.

Now, the common factors can be found like this.

767:13x 59

668:2x 2x 167

455:5x 7x 13

121:11x 11

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

13 = 13

Therefore, the value for common factors is 13.

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 = 28207759580/(1x13)

LCM = 28207759580/13

LCM = 2169827660

Thus, we can understand that the LCM of 767,668,455,121 is 2169827660.
