Given numbers are 794,128,336,421

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

The LCM of 794,128,336,421 is 449264256.

Find LCM of 794,128,336,421 with Prime Factorization

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

2 x 2 x 2 x 2 x 397 x 8 x 21 x 421 = 449264256

Therefore, the lowest common multiple of 794,128,336,421 is 449264256.

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.

794 x 128 x 336 x 421 = 14376456192

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.

794 : 1, 2, 397, 794

128 : 1, 2, 4, 8, 16, 32, 64, 128

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 794,128,336,421, is 1.

Now, the common factors can be found like this.

794:2x 397

128:2x 2x 2x 2x 2x 2x 2

336:2x 2x 2x 2x 3x 7

421:421

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 2 = 32

Therefore, the value for common factors is 32.

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 = 14376456192/(1x32)

LCM = 14376456192/32

LCM = 449264256

Thus, we can understand that the LCM of 794,128,336,421 is 449264256.
