Given numbers are 678,721,652,871

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

The LCM of 678,721,652,871 is 138803594748.

Find LCM of 678,721,652,871 with Prime Factorization

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

2 x 339 x 721 x 326 x 871 = 138803594748

Therefore, the lowest common multiple of 678,721,652,871 is 138803594748.

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.

678 x 721 x 652 x 871 = 277607189496

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.

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

721 : 1, 7, 103, 721

652 : 1, 2, 4, 163, 326, 652

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,721,652,871, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

721:7x 103

652:2x 2x 163

871:13x 67

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

2 = 2

Therefore, the value for common factors is 2.

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 = 277607189496/(1x2)

LCM = 277607189496/2

LCM = 138803594748

Thus, we can understand that the LCM of 678,721,652,871 is 138803594748.
