The LCM of 494,855,427,421 is 3996220410.

Find LCM of 494,855,427,421 with Prime Factorization


19 494, 855, 427, 421
26, 45, 427, 421

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

19 x 26 x 45 x 427 x 421 = 3996220410

Therefore, the lowest common multiple of 494,855,427,421 is 3996220410.

LCM Formula to Find Lowest Common Multiple of 494,855,427,421

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.

494 x 855 x 427 x 421 = 75928187790

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.

494 : 1, 2, 13, 19, 26, 38, 247, 494

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

427 : 1, 7, 61, 427

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,855,427,421, is 1.

Now, the common factors can be found like this.

494:2x 13x 19

855:3x 3x 5x 19

427:7x 61

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.

19 = 19

Therefore, the value for common factors is 19.

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 = 75928187790/(1x19)

LCM = 75928187790/19

LCM = 3996220410

Thus, we can understand that the LCM of 494,855,427,421 is 3996220410.
