Given numbers are 434,391,871,154

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

The LCM of 434,391,871,154 is 1625838214.

Find LCM of 434,391,871,154 with Prime Factorization

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

2 x 7 x 31 x 391 x 871 x 11 = 1625838214

Therefore, the lowest common multiple of 434,391,871,154 is 1625838214.

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.

434 x 391 x 871 x 154 = 22761734996

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.

434 : 1, 2, 7, 14, 31, 62, 217, 434

391 : 1, 17, 23, 391

871 : 1, 13, 67, 871

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,391,871,154, is 1.

Now, the common factors can be found like this.

434:2x 7x 31

391:17x 23

871:13x 67

154:2x 7x 11

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 22761734996/(1x14)

LCM = 22761734996/14

LCM = 1625838214

Thus, we can understand that the LCM of 434,391,871,154 is 1625838214.
