Given numbers are 208,296,438,821

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

The LCM of 208,296,438,821 is 1383733104.

Find LCM of 208,296,438,821 with Prime Factorization

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

2 x 2 x 2 x 26 x 37 x 219 x 821 = 1383733104

Therefore, the lowest common multiple of 208,296,438,821 is 1383733104.

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.

208 x 296 x 438 x 821 = 22139729664

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.

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

296 : 1, 2, 4, 8, 37, 74, 148, 296

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

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,296,438,821, is 1.

Now, the common factors can be found like this.

208:2x 2x 2x 2x 13

296:2x 2x 2x 37

438:2x 3x 73

821:821

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 2 = 16

Therefore, the value for common factors is 16.

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 = 22139729664/(1x16)

LCM = 22139729664/16

LCM = 1383733104

Thus, we can understand that the LCM of 208,296,438,821 is 1383733104.
