Calculate the LCM of 493,390,909,447

Given numbers are 493,390,909,447

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

The LCM of 493,390,909,447 is 8680413690.

Find LCM of 493,390,909,447 with Prime Factorization


3 493, 390, 909, 447
493, 130, 303, 149

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

3 x 493 x 130 x 303 x 149 = 8680413690

Therefore, the lowest common multiple of 493,390,909,447 is 8680413690.

LCM Formula to Find Lowest Common Multiple of 493,390,909,447

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.

493 x 390 x 909 x 447 = 78123723210

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.

493 : 1, 17, 29, 493

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

909 : 1, 3, 9, 101, 303, 909

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,390,909,447, is 1.

Now, the common factors can be found like this.

493:17x 29

390:2x 3x 5x 13

909:3x 3x 101

447:3x 149

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 78123723210/(1x9)

LCM = 78123723210/9

LCM = 8680413690

Thus, we can understand that the LCM of 493,390,909,447 is 8680413690.
