The LCM of 492,579,861,421 is 279835332.

Find LCM of 492,579,861,421 with Prime Factorization


3 492, 579, 861, 421
41 164, 193, 287, 421
4, 193, 7, 421

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

3 x 41 x 4 x 193 x 7 x 421 = 279835332

Therefore, the lowest common multiple of 492,579,861,421 is 279835332.

LCM Formula to Find Lowest Common Multiple of 492,579,861,421

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.

492 x 579 x 861 x 421 = 103259237508

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.

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

579 : 1, 3, 193, 579

861 : 1, 3, 7, 21, 41, 123, 287, 861

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,579,861,421, is 1.

Now, the common factors can be found like this.

492:2x 2x 3x 41

579:3x 193

861:3x 7x 41

421:421

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

3x 3x 41 = 369

Therefore, the value for common factors is 369.

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 = 103259237508/(1x369)

LCM = 103259237508/369

LCM = 279835332

Thus, we can understand that the LCM of 492,579,861,421 is 279835332.
