Calculate the LCM of 308,961,438,257

Given numbers are 308,961,438,257

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

The LCM of 308,961,438,257 is 16659092604.

Find LCM of 308,961,438,257 with Prime Factorization


2 308, 961, 438, 257
154, 961, 219, 257

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

2 x 154 x 961 x 219 x 257 = 16659092604

Therefore, the lowest common multiple of 308,961,438,257 is 16659092604.

LCM Formula to Find Lowest Common Multiple of 308,961,438,257

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.

308 x 961 x 438 x 257 = 33318185208

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.

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

961 : 1, 31, 961

438 : 1, 2, 3, 6, 73, 146, 219, 438

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,961,438,257, is 1.

Now, the common factors can be found like this.

308:2x 2x 7x 11

961:31x 31

438:2x 3x 73

257:257

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

2 = 2

Therefore, the value for common factors is 2.

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 = 33318185208/(1x2)

LCM = 33318185208/2

LCM = 16659092604

Thus, we can understand that the LCM of 308,961,438,257 is 16659092604.
