Given numbers are 638,934,728,182,637

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

The LCM of 638,934,728,182,637 is 759166408.

Find LCM of 638,934,728,182,637 with Prime Factorization

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

2 x 7 x 13 x 319 x 467 x 4 x 1 x 7 = 759166408

Therefore, the lowest common multiple of 638,934,728,182,637 is 759166408.

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.

638 x 934 x 728 x 182 x 637 = 50293256197184

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

934 : 1, 2, 467, 934

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

182 : 1, 2, 7, 13, 14, 26, 91, 182

637 : 1, 7, 13, 49, 91, 637

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,934,728,182,637, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

934:2x 467

728:2x 2x 2x 7x 13

182:2x 7x 13

637:7x 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.

2x 2x 2x 7x 7x 13x 13 = 66248

Therefore, the value for common factors is 66248.

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 = 50293256197184/(1x66248)

LCM = 50293256197184/66248

LCM = 759166408

Thus, we can understand that the LCM of 638,934,728,182,637 is 759166408.
