Given numbers are 1256,1298

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

The LCM of 1256,1298 is 815144.

Find LCM of 1256,1298 with Prime Factorization

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

2 x 628 x 649 = 815144

Therefore, the lowest common multiple of 1256,1298 is 815144.

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.

1256 x 1298 = 1630288

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.

1256 : 1, 2, 4, 8, 157, 314, 628, 1256

1298 : 1, 2, 11, 22, 59, 118, 649, 1298

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1256,1298, is 2.

Now, the common factors can be found like this.

1256:2x 2x 2x 157

1298:2x 11x 59

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 = 1630288/(2x1)

LCM = 1630288/2

LCM = 815144

Thus, we can understand that the LCM of 1256,1298 is 815144.
