Given numbers are 402,109,218,860

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

The LCM of 402,109,218,860 is 18841740.

Find LCM of 402,109,218,860 with Prime Factorization

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

2 x 109 x 201 x 1 x 1 x 430 = 18841740

Therefore, the lowest common multiple of 402,109,218,860 is 18841740.

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.

402 x 109 x 218 x 860 = 8214998640

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

109 : 1, 109

218 : 1, 2, 109, 218

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,109,218,860, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

109:109

218:2x 109

860:2x 2x 5x 43

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 109 = 436

Therefore, the value for common factors is 436.

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 = 8214998640/(1x436)

LCM = 8214998640/436

LCM = 18841740

Thus, we can understand that the LCM of 402,109,218,860 is 18841740.
