Given numbers are 218,473,978,540

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

The LCM of 218,473,978,540 is 4538047140.

Find LCM of 218,473,978,540 with Prime Factorization

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

2 x 3 x 109 x 473 x 163 x 90 = 4538047140

Therefore, the lowest common multiple of 218,473,978,540 is 4538047140.

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.

218 x 473 x 978 x 540 = 54456565680

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.

218 : 1, 2, 109, 218

473 : 1, 11, 43, 473

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

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,473,978,540, is 1.

Now, the common factors can be found like this.

218:2x 109

473:11x 43

978:2x 3x 163

540:2x 2x 3x 3x 3x 5

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 3 = 12

Therefore, the value for common factors is 12.

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 = 54456565680/(1x12)

LCM = 54456565680/12

LCM = 4538047140

Thus, we can understand that the LCM of 218,473,978,540 is 4538047140.
