Given numbers are 189,281,978,226

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

The LCM of 189,281,978,226 is 1956429342.

Find LCM of 189,281,978,226 with Prime Factorization

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

2 x 3 x 63 x 281 x 163 x 113 = 1956429342

Therefore, the lowest common multiple of 189,281,978,226 is 1956429342.

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.

189 x 281 x 978 x 226 = 11738576052

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

281 : 1, 281

978 : 1, 2, 3, 6, 163, 326, 489, 978

226 : 1, 2, 113, 226

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,281,978,226, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

281:281

978:2x 3x 163

226:2x 113

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 11738576052/(1x6)

LCM = 11738576052/6

LCM = 1956429342

Thus, we can understand that the LCM of 189,281,978,226 is 1956429342.
