Given numbers are 631,218,909,978,930

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

The LCM of 631,218,909,978,930 is 3159141208830.

Find LCM of 631,218,909,978,930 with Prime Factorization

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

2 x 3 x 631 x 109 x 303 x 163 x 155 = 3159141208830

Therefore, the lowest common multiple of 631,218,909,978,930 is 3159141208830.

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.

631 x 218 x 909 x 978 x 930 = 113729083517880

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.

631 : 1, 631

218 : 1, 2, 109, 218

909 : 1, 3, 9, 101, 303, 909

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

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,218,909,978,930, is 1.

Now, the common factors can be found like this.

631:631

218:2x 109

909:3x 3x 101

978:2x 3x 163

930:2x 3x 5x 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 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 113729083517880/(1x36)

LCM = 113729083517880/36

LCM = 3159141208830

Thus, we can understand that the LCM of 631,218,909,978,930 is 3159141208830.
