Given numbers are 218,654,545,856

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

The LCM of 218,654,545,856 is 1399560.

Find LCM of 218,654,545,856 with Prime Factorization

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

2 x 109 x 1 x 3 x 5 x 428 = 1399560

Therefore, the lowest common multiple of 218,654,545,856 is 1399560.

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 654 x 545 x 856 = 66512689440

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

654 : 1, 2, 3, 6, 109, 218, 327, 654

545 : 1, 5, 109, 545

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,654,545,856, is 1.

Now, the common factors can be found like this.

218:2x 109

654:2x 3x 109

545:5x 109

856:2x 2x 2x 107

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 109x 109 = 47524

Therefore, the value for common factors is 47524.

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 = 66512689440/(1x47524)

LCM = 66512689440/47524

LCM = 1399560

Thus, we can understand that the LCM of 218,654,545,856 is 1399560.
