Given numbers are 842,978,340,827

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

The LCM of 842,978,340,827 is 57886245420.

Find LCM of 842,978,340,827 with Prime Factorization

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

2 x 421 x 489 x 170 x 827 = 57886245420

Therefore, the lowest common multiple of 842,978,340,827 is 57886245420.

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 978 x 340 x 827 = 231544981680

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

978 : 1, 2, 3, 6, 163, 326, 489, 978

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

827 : 1, 827

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,978,340,827, is 1.

Now, the common factors can be found like this.

842:2x 421

978:2x 3x 163

340:2x 2x 5x 17

827:827

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 = 231544981680/(1x4)

LCM = 231544981680/4

LCM = 57886245420

Thus, we can understand that the LCM of 842,978,340,827 is 57886245420.
