Given numbers are 978,652,889,217

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

The LCM of 978,652,889,217 is 53905404.

Find LCM of 978,652,889,217 with Prime Factorization

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

2 x 7 x 163 x 3 x 2 x 127 x 31 = 53905404

Therefore, the lowest common multiple of 978,652,889,217 is 53905404.

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 652 x 889 x 217 = 123012131928

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

652 : 1, 2, 4, 163, 326, 652

889 : 1, 7, 127, 889

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,652,889,217, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

652:2x 2x 163

889:7x 127

217:7x 31

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

2x 7x 163 = 2282

Therefore, the value for common factors is 2282.

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 = 123012131928/(1x2282)

LCM = 123012131928/2282

LCM = 53905404

Thus, we can understand that the LCM of 978,652,889,217 is 53905404.
