Given numbers are 487,423,122,338

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

The LCM of 487,423,122,338 is 4247328618.

Find LCM of 487,423,122,338 with Prime Factorization

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

2 x 487 x 423 x 61 x 169 = 4247328618

Therefore, the lowest common multiple of 487,423,122,338 is 4247328618.

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.

487 x 423 x 122 x 338 = 8494657236

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.

487 : 1, 487

423 : 1, 3, 9, 47, 141, 423

122 : 1, 2, 61, 122

338 : 1, 2, 13, 26, 169, 338

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,423,122,338, is 1.

Now, the common factors can be found like this.

487:487

423:3x 3x 47

122:2x 61

338:2x 13x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 8494657236/(1x2)

LCM = 8494657236/2

LCM = 4247328618

Thus, we can understand that the LCM of 487,423,122,338 is 4247328618.
