Given numbers are 42,142,132

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

The LCM of 42,142,132 is 65604.

Find LCM of 42,142,132 with Prime Factorization

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

2 x 3 x 7 x 71 x 22 = 65604

Therefore, the lowest common multiple of 42,142,132 is 65604.

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 142 x 132 = 787248

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

142 : 1, 2, 71, 142

132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 42,142,132, is 2.

Now, the common factors can be found like this.

42:2x 3x 7

142:2x 71

132:2x 2x 3x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 787248/(2x6)

LCM = 787248/12

LCM = 65604

Thus, we can understand that the LCM of 42,142,132 is 65604.

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

• LCM of 89, 840, 848
• LCM of 40, 551, 793
