Given numbers are 871,782,698,678

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

The LCM of 871,782,698,678 is 80584224942.

Find LCM of 871,782,698,678 with Prime Factorization

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

2 x 871 x 391 x 349 x 339 = 80584224942

Therefore, the lowest common multiple of 871,782,698,678 is 80584224942.

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 782 x 698 x 678 = 322336899768

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

782 : 1, 2, 17, 23, 34, 46, 391, 782

698 : 1, 2, 349, 698

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,782,698,678, is 1.

Now, the common factors can be found like this.

871:13x 67

782:2x 17x 23

698:2x 349

678:2x 3x 113

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 322336899768/(1x4)

LCM = 322336899768/4

LCM = 80584224942

Thus, we can understand that the LCM of 871,782,698,678 is 80584224942.
