Given numbers are 31,93,742

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

The LCM of 31,93,742 is 69006.

Find LCM of 31,93,742 with Prime Factorization

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

31 x 1 x 3 x 742 = 69006

Therefore, the lowest common multiple of 31,93,742 is 69006.

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.

31 x 93 x 742 = 2139186

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.

31 : 1, 31

93 : 1, 3, 31, 93

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 31,93,742, is 1.

Now, the common factors can be found like this.

31:31

93:3x 31

742:2x 7x 53

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

31 = 31

Therefore, the value for common factors is 31.

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 = 2139186/(1x31)

LCM = 2139186/31

LCM = 69006

Thus, we can understand that the LCM of 31,93,742 is 69006.

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

• LCM of 93, 11, 220
• LCM of 18, 83, 309
