Calculate the LCM of 178,337,646,647

Given numbers are 178,337,646,647

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

The LCM of 178,337,646,647 is 12535934266.

Find LCM of 178,337,646,647 with Prime Factorization


2 178, 337, 646, 647
89, 337, 323, 647

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

2 x 89 x 337 x 323 x 647 = 12535934266

Therefore, the lowest common multiple of 178,337,646,647 is 12535934266.

LCM Formula to Find Lowest Common Multiple of 178,337,646,647

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.

178 x 337 x 646 x 647 = 25071868532

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.

178 : 1, 2, 89, 178

337 : 1, 337

646 : 1, 2, 17, 19, 34, 38, 323, 646

647 : 1, 647

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,337,646,647, is 1.

Now, the common factors can be found like this.

178:2x 89

337:337

646:2x 17x 19

647:647

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 = 25071868532/(1x2)

LCM = 25071868532/2

LCM = 12535934266

Thus, we can understand that the LCM of 178,337,646,647 is 12535934266.
