Given numbers are 842,994,421,368

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

The LCM of 842,994,421,368 is 76999216.

Find LCM of 842,994,421,368 with Prime Factorization

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

2 x 421 x 1 x 497 x 1 x 184 = 76999216

Therefore, the lowest common multiple of 842,994,421,368 is 76999216.

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 994 x 421 x 368 = 129666679744

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

994 : 1, 2, 7, 14, 71, 142, 497, 994

421 : 1, 421

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,994,421,368, is 1.

Now, the common factors can be found like this.

842:2x 421

994:2x 7x 71

421:421

368:2x 2x 2x 2x 23

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

2x 2x 421 = 1684

Therefore, the value for common factors is 1684.

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 = 129666679744/(1x1684)

LCM = 129666679744/1684

LCM = 76999216

Thus, we can understand that the LCM of 842,994,421,368 is 76999216.
