Given numbers are 647,810,480,776,402

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

The LCM of 647,810,480,776,402 is 54494894880.

Find LCM of 647,810,480,776,402 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 647 x 27 x 4 x 97 x 67 = 54494894880

Therefore, the lowest common multiple of 647,810,480,776,402 is 54494894880.

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.

647 x 810 x 480 x 776 x 402 = 78472648627200

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.

647 : 1, 647

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,810,480,776,402, is 1.

Now, the common factors can be found like this.

647:647

810:2x 3x 3x 3x 3x 5

480:2x 2x 2x 2x 2x 3x 5

776:2x 2x 2x 97

402:2x 3x 67

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 2x 3x 3x 5 = 1440

Therefore, the value for common factors is 1440.

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 = 78472648627200/(1x1440)

LCM = 78472648627200/1440

LCM = 54494894880

Thus, we can understand that the LCM of 647,810,480,776,402 is 54494894880.
