Given numbers are 211,470,422,978

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

The LCM of 211,470,422,978 is 48494130.

Find LCM of 211,470,422,978 with Prime Factorization

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

2 x 211 x 1 x 235 x 1 x 489 = 48494130

Therefore, the lowest common multiple of 211,470,422,978 is 48494130.

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.

211 x 470 x 422 x 978 = 40929045720

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.

211 : 1, 211

470 : 1, 2, 5, 10, 47, 94, 235, 470

422 : 1, 2, 211, 422

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,470,422,978, is 1.

Now, the common factors can be found like this.

211:211

470:2x 5x 47

422:2x 211

978:2x 3x 163

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 211 = 844

Therefore, the value for common factors is 844.

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 = 40929045720/(1x844)

LCM = 40929045720/844

LCM = 48494130

Thus, we can understand that the LCM of 211,470,422,978 is 48494130.
