Given numbers are 1282,1138

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

The LCM of 1282,1138 is 729458.

Find LCM of 1282,1138 with Prime Factorization

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

2 x 641 x 569 = 729458

Therefore, the lowest common multiple of 1282,1138 is 729458.

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.

1282 x 1138 = 1458916

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.

1282 : 1, 2, 641, 1282

1138 : 1, 2, 569, 1138

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1282,1138, is 2.

Now, the common factors can be found like this.

1282:2x 641

1138:2x 569

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

= 1

Therefore, the value for common factors is 1.

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 = 1458916/(2x1)

LCM = 1458916/2

LCM = 729458

Thus, we can understand that the LCM of 1282,1138 is 729458.
