Given numbers are 208,238,860,648

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

The LCM of 208,238,860,648 is 431056080.

Find LCM of 208,238,860,648 with Prime Factorization

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

2 x 2 x 2 x 26 x 119 x 215 x 81 = 431056080

Therefore, the lowest common multiple of 208,238,860,648 is 431056080.

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 238 x 860 x 648 = 27587589120

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

238 : 1, 2, 7, 14, 17, 34, 119, 238

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,238,860,648, is 2.

Now, the common factors can be found like this.

208:2x 2x 2x 2x 13

238:2x 7x 17

860:2x 2x 5x 43

648:2x 2x 2x 3x 3x 3x 3

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 = 27587589120/(2x32)

LCM = 27587589120/64

LCM = 431056080

Thus, we can understand that the LCM of 208,238,860,648 is 431056080.
