Calculate the LCM of 646,753,990,323

Given numbers are 646,753,990,323

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

The LCM of 646,753,990,323 is 80262270.

Find LCM of 646,753,990,323 with Prime Factorization


2 646, 753, 990, 323
3 323, 753, 495, 323
17 323, 251, 165, 323
19 19, 251, 165, 19
1, 251, 165, 1

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

2 x 3 x 17 x 19 x 1 x 251 x 165 x 1 = 80262270

Therefore, the lowest common multiple of 646,753,990,323 is 80262270.

LCM Formula to Find Lowest Common Multiple of 646,753,990,323

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.

646 x 753 x 990 x 323 = 155548279260

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.

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

753 : 1, 3, 251, 753

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

323 : 1, 17, 19, 323

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,753,990,323, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

753:3x 251

990:2x 3x 3x 5x 11

323:17x 19

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

2x 3x 17x 19 = 1938

Therefore, the value for common factors is 1938.

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 = 155548279260/(1x1938)

LCM = 155548279260/1938

LCM = 80262270

Thus, we can understand that the LCM of 646,753,990,323 is 80262270.
