Calculate the LCM of 663,446,427,620

Given numbers are 663,446,427,620

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

The LCM of 663,446,427,620 is 39141544260.

Find LCM of 663,446,427,620 with Prime Factorization


2 663, 446, 427, 620
663, 223, 427, 310

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

2 x 663 x 223 x 427 x 310 = 39141544260

Therefore, the lowest common multiple of 663,446,427,620 is 39141544260.

LCM Formula to Find Lowest Common Multiple of 663,446,427,620

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.

663 x 446 x 427 x 620 = 78283088520

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

446 : 1, 2, 223, 446

427 : 1, 7, 61, 427

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,446,427,620, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

446:2x 223

427:7x 61

620:2x 2x 5x 31

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 = 78283088520/(1x2)

LCM = 78283088520/2

LCM = 39141544260

Thus, we can understand that the LCM of 663,446,427,620 is 39141544260.
