Given numbers are 137,65,728

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

The LCM of 137,65,728 is 498680.

Find LCM of 137,65,728 with Prime Factorization

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

13 x 137 x 5 x 56 = 498680

Therefore, the lowest common multiple of 137,65,728 is 498680.

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.

137 x 65 x 728 = 6482840

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.

137 : 1, 137

65 : 1, 5, 13, 65

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,65,728, is 1.

Now, the common factors can be found like this.

137:137

65:5x 13

728:2x 2x 2x 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.

13 = 13

Therefore, the value for common factors is 13.

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 = 6482840/(1x13)

LCM = 6482840/13

LCM = 498680

Thus, we can understand that the LCM of 137,65,728 is 498680.

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

• LCM of 600, 31, 647
• LCM of 995, 86, 349
