Given numbers are 776,754,455,520,621

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

The LCM of 776,754,455,520,621 is 6358617720.

Find LCM of 776,754,455,520,621 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 97 x 29 x 7 x 1 x 621 = 6358617720

Therefore, the lowest common multiple of 776,754,455,520,621 is 6358617720.

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.

776 x 754 x 455 x 520 x 621 = 85968511574400

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.

776 : 1, 2, 4, 8, 97, 194, 388, 776

754 : 1, 2, 13, 26, 29, 58, 377, 754

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

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 776,754,455,520,621, is 1.

Now, the common factors can be found like this.

776:2x 2x 2x 97

754:2x 13x 29

455:5x 7x 13

520:2x 2x 2x 5x 13

621:3x 3x 3x 23

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

2x 2x 2x 2x 5x 13x 13 = 13520

Therefore, the value for common factors is 13520.

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 = 85968511574400/(1x13520)

LCM = 85968511574400/13520

LCM = 6358617720

Thus, we can understand that the LCM of 776,754,455,520,621 is 6358617720.
