Given numbers are 42,27,994

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

The LCM of 42,27,994 is 26838.

Find LCM of 42,27,994 with Prime Factorization

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

2 x 3 x 7 x 1 x 9 x 71 = 26838

Therefore, the lowest common multiple of 42,27,994 is 26838.

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.

42 x 27 x 994 = 1127196

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.

42 : 1, 2, 3, 6, 7, 14, 21, 42

27 : 1, 3, 9, 27

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 42,27,994, is 1.

Now, the common factors can be found like this.

42:2x 3x 7

27:3x 3x 3

994:2x 7x 71

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

2x 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 1127196/(1x42)

LCM = 1127196/42

LCM = 26838

Thus, we can understand that the LCM of 42,27,994 is 26838.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 11, 69, 509
• LCM of 79, 21, 719
