Given numbers are 438,669,208,386

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

The LCM of 438,669,208,386 is 1960512528.

Find LCM of 438,669,208,386 with Prime Factorization

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

2 x 3 x 73 x 223 x 104 x 193 = 1960512528

Therefore, the lowest common multiple of 438,669,208,386 is 1960512528.

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.

438 x 669 x 208 x 386 = 23526150336

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

669 : 1, 3, 223, 669

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,669,208,386, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

669:3x 223

208:2x 2x 2x 2x 13

386:2x 193

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 3 = 12

Therefore, the value for common factors is 12.

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 = 23526150336/(1x12)

LCM = 23526150336/12

LCM = 1960512528

Thus, we can understand that the LCM of 438,669,208,386 is 1960512528.
