Given numbers are 212,571,954,221

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

The LCM of 212,571,954,221 is 240772428.

Find LCM of 212,571,954,221 with Prime Factorization

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

2 x 53 x 2 x 571 x 9 x 221 = 240772428

Therefore, the lowest common multiple of 212,571,954,221 is 240772428.

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.

212 x 571 x 954 x 221 = 25521877368

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.

212 : 1, 2, 4, 53, 106, 212

571 : 1, 571

954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,571,954,221, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

571:571

954:2x 3x 3x 53

221:13x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 25521877368/(1x106)

LCM = 25521877368/106

LCM = 240772428

Thus, we can understand that the LCM of 212,571,954,221 is 240772428.
