Given numbers are 391,793,871,454,121

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

The LCM of 391,793,871,454,121 is 1141211056414.

Find LCM of 391,793,871,454,121 with Prime Factorization

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

13 x 391 x 61 x 67 x 454 x 121 = 1141211056414

Therefore, the lowest common multiple of 391,793,871,454,121 is 1141211056414.

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.

391 x 793 x 871 x 454 x 121 = 14835743733382

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.

391 : 1, 17, 23, 391

793 : 1, 13, 61, 793

871 : 1, 13, 67, 871

454 : 1, 2, 227, 454

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,793,871,454,121, is 1.

Now, the common factors can be found like this.

391:17x 23

793:13x 61

871:13x 67

454:2x 227

121:11x 11

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

13 = 13

Therefore, the value for common factors is 13.

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 = 14835743733382/(1x13)

LCM = 14835743733382/13

LCM = 1141211056414

Thus, we can understand that the LCM of 391,793,871,454,121 is 1141211056414.
