Given numbers are 978,103,163,218

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

The LCM of 978,103,163,218 is 10980006.

Find LCM of 978,103,163,218 with Prime Factorization

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

2 x 163 x 3 x 103 x 1 x 109 = 10980006

Therefore, the lowest common multiple of 978,103,163,218 is 10980006.

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.

978 x 103 x 163 x 218 = 3579481956

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.

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

103 : 1, 103

163 : 1, 163

218 : 1, 2, 109, 218

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,103,163,218, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

103:103

163:163

218:2x 109

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 = 3579481956/(1x326)

LCM = 3579481956/326

LCM = 10980006

Thus, we can understand that the LCM of 978,103,163,218 is 10980006.
