Given numbers are 871,421,532,654,920

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

The LCM of 871,421,532,654,920 is 14671937618520.

Find LCM of 871,421,532,654,920 with Prime Factorization

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

2 x 2 x 871 x 421 x 133 x 327 x 230 = 14671937618520

Therefore, the lowest common multiple of 871,421,532,654,920 is 14671937618520.

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.

871 x 421 x 532 x 654 x 920 = 117375500948160

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.

871 : 1, 13, 67, 871

421 : 1, 421

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

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

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,421,532,654,920, is 1.

Now, the common factors can be found like this.

871:13x 67

421:421

532:2x 2x 7x 19

654:2x 3x 109

920:2x 2x 2x 5x 23

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 2 = 8

Therefore, the value for common factors is 8.

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 = 117375500948160/(1x8)

LCM = 117375500948160/8

LCM = 14671937618520

Thus, we can understand that the LCM of 871,421,532,654,920 is 14671937618520.
