Given numbers are 861,694,871,310

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

The LCM of 861,694,871,310 is 80670077670.

Find LCM of 861,694,871,310 with Prime Factorization

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

2 x 861 x 347 x 871 x 155 = 80670077670

Therefore, the lowest common multiple of 861,694,871,310 is 80670077670.

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.

861 x 694 x 871 x 310 = 161340155340

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

694 : 1, 2, 347, 694

871 : 1, 13, 67, 871

310 : 1, 2, 5, 10, 31, 62, 155, 310

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,694,871,310, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

694:2x 347

871:13x 67

310:2x 5x 31

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 = 161340155340/(1x2)

LCM = 161340155340/2

LCM = 80670077670

Thus, we can understand that the LCM of 861,694,871,310 is 80670077670.
