Calculate the LCM of 608,397,794,661

Given numbers are 608,397,794,661

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

The LCM of 608,397,794,661 is 159549536.

Find LCM of 608,397,794,661 with Prime Factorization


2 608, 397, 794, 661
397 304, 397, 397, 661
304, 1, 1, 661

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

2 x 397 x 304 x 1 x 1 x 661 = 159549536

Therefore, the lowest common multiple of 608,397,794,661 is 159549536.

LCM Formula to Find Lowest Common Multiple of 608,397,794,661

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.

608 x 397 x 794 x 661 = 126682331584

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.

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

397 : 1, 397

794 : 1, 2, 397, 794

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 608,397,794,661, is 1.

Now, the common factors can be found like this.

608:2x 2x 2x 2x 2x 19

397:397

794:2x 397

661:661

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

2x 397 = 794

Therefore, the value for common factors is 794.

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 = 126682331584/(1x794)

LCM = 126682331584/794

LCM = 159549536

Thus, we can understand that the LCM of 608,397,794,661 is 159549536.
