Given numbers are 720,381,455,994,776

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

The LCM of 720,381,455,994,776 is 57307002480.

Find LCM of 720,381,455,994,776 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 7 x 6 x 127 x 13 x 71 x 97 = 57307002480

Therefore, the lowest common multiple of 720,381,455,994,776 is 57307002480.

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.

720 x 381 x 455 x 994 x 776 = 96275764166400

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

381 : 1, 3, 127, 381

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

994 : 1, 2, 7, 14, 71, 142, 497, 994

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,381,455,994,776, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

381:3x 127

455:5x 7x 13

994:2x 7x 71

776:2x 2x 2x 97

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 3x 5x 7 = 1680

Therefore, the value for common factors is 1680.

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 = 96275764166400/(1x1680)

LCM = 96275764166400/1680

LCM = 57307002480

Thus, we can understand that the LCM of 720,381,455,994,776 is 57307002480.
