Calculate the LCM of 298,253,256,642

Given numbers are 298,253,256,642

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

The LCM of 298,253,256,642 is 3097788672.

Find LCM of 298,253,256,642 with Prime Factorization


2 298, 253, 256, 642
149, 253, 128, 321

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

2 x 149 x 253 x 128 x 321 = 3097788672

Therefore, the lowest common multiple of 298,253,256,642 is 3097788672.

LCM Formula to Find Lowest Common Multiple of 298,253,256,642

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.

298 x 253 x 256 x 642 = 12391154688

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.

298 : 1, 2, 149, 298

253 : 1, 11, 23, 253

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,253,256,642, is 1.

Now, the common factors can be found like this.

298:2x 149

253:11x 23

256:2x 2x 2x 2x 2x 2x 2x 2

642:2x 3x 107

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 12391154688/(1x4)

LCM = 12391154688/4

LCM = 3097788672

Thus, we can understand that the LCM of 298,253,256,642 is 3097788672.
