Given numbers are 663,389,253,871,520

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

The LCM of 663,389,253,871,520 is 174871262280.

Find LCM of 663,389,253,871,520 with Prime Factorization

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

13 x 51 x 389 x 253 x 67 x 40 = 174871262280

Therefore, the lowest common multiple of 663,389,253,871,520 is 174871262280.

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 389 x 253 x 871 x 520 = 29553243325320

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

389 : 1, 389

253 : 1, 11, 23, 253

871 : 1, 13, 67, 871

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,389,253,871,520, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

389:389

253:11x 23

871:13x 67

520:2x 2x 2x 5x 13

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 29553243325320/(1x169)

LCM = 29553243325320/169

LCM = 174871262280

Thus, we can understand that the LCM of 663,389,253,871,520 is 174871262280.
