Given numbers are 326,167,978,421

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

The LCM of 326,167,978,421 is 68760246.

Find LCM of 326,167,978,421 with Prime Factorization

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

2 x 163 x 1 x 167 x 3 x 421 = 68760246

Therefore, the lowest common multiple of 326,167,978,421 is 68760246.

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.

326 x 167 x 978 x 421 = 22415840196

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.

326 : 1, 2, 163, 326

167 : 1, 167

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

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,167,978,421, is 1.

Now, the common factors can be found like this.

326:2x 163

167:167

978:2x 3x 163

421:421

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

2x 163 = 326

Therefore, the value for common factors is 326.

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 = 22415840196/(1x326)

LCM = 22415840196/326

LCM = 68760246

Thus, we can understand that the LCM of 326,167,978,421 is 68760246.
