Given numbers are 218,178,817,252,178

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

The LCM of 218,178,817,252,178 is 1997280684.

Find LCM of 218,178,817,252,178 with Prime Factorization

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

2 x 89 x 109 x 1 x 817 x 126 x 1 = 1997280684

Therefore, the lowest common multiple of 218,178,817,252,178 is 1997280684.

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 178 x 817 x 252 x 178 = 1422063847008

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

178 : 1, 2, 89, 178

817 : 1, 19, 43, 817

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

178 : 1, 2, 89, 178

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,178,817,252,178, is 1.

Now, the common factors can be found like this.

218:2x 109

178:2x 89

817:19x 43

252:2x 2x 3x 3x 7

178:2x 89

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 2x 89 = 712

Therefore, the value for common factors is 712.

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 = 1422063847008/(1x712)

LCM = 1422063847008/712

LCM = 1997280684

Thus, we can understand that the LCM of 218,178,817,252,178 is 1997280684.
