Given numbers are 842,554,786,871

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

The LCM of 842,554,786,871 is 79836697902.

Find LCM of 842,554,786,871 with Prime Factorization

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

2 x 421 x 277 x 393 x 871 = 79836697902

Therefore, the lowest common multiple of 842,554,786,871 is 79836697902.

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.

842 x 554 x 786 x 871 = 319346791608

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.

842 : 1, 2, 421, 842

554 : 1, 2, 277, 554

786 : 1, 2, 3, 6, 131, 262, 393, 786

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,554,786,871, is 1.

Now, the common factors can be found like this.

842:2x 421

554:2x 277

786:2x 3x 131

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.

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 = 319346791608/(1x4)

LCM = 319346791608/4

LCM = 79836697902

Thus, we can understand that the LCM of 842,554,786,871 is 79836697902.
