Given numbers are 253,42,273

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

The LCM of 253,42,273 is 138138.

Find LCM of 253,42,273 with Prime Factorization

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

3 x 7 x 253 x 2 x 13 = 138138

Therefore, the lowest common multiple of 253,42,273 is 138138.

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.

253 x 42 x 273 = 2900898

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.

253 : 1, 11, 23, 253

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

273 : 1, 3, 7, 13, 21, 39, 91, 273

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,42,273, is 1.

Now, the common factors can be found like this.

253:11x 23

42:2x 3x 7

273:3x 7x 13

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 2900898/(1x21)

LCM = 2900898/21

LCM = 138138

Thus, we can understand that the LCM of 253,42,273 is 138138.

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

• LCM of 794, 24, 800
• LCM of 756, 84, 144
