Given numbers are 647,117,739,728

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

The LCM of 647,117,739,728 is 3132727416.

Find LCM of 647,117,739,728 with Prime Factorization

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

13 x 647 x 9 x 739 x 56 = 3132727416

Therefore, the lowest common multiple of 647,117,739,728 is 3132727416.

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 117 x 739 x 728 = 40725456408

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

117 : 1, 3, 9, 13, 39, 117

739 : 1, 739

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,117,739,728, is 1.

Now, the common factors can be found like this.

647:647

117:3x 3x 13

739:739

728:2x 2x 2x 7x 13

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 = 40725456408/(1x13)

LCM = 40725456408/13

LCM = 3132727416

Thus, we can understand that the LCM of 647,117,739,728 is 3132727416.
