Given numbers are 420,559,496,193,386

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

The LCM of 420,559,496,193,386 is 5618754960.

Find LCM of 420,559,496,193,386 with Prime Factorization

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

2 x 2 x 193 x 105 x 559 x 124 x 1 x 1 = 5618754960

Therefore, the lowest common multiple of 420,559,496,193,386 is 5618754960.

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.

420 x 559 x 496 x 193 x 386 = 8675357658240

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

559 : 1, 13, 43, 559

496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496

193 : 1, 193

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,559,496,193,386, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

559:13x 43

496:2x 2x 2x 2x 31

193:193

386:2x 193

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

2x 2x 2x 193 = 1544

Therefore, the value for common factors is 1544.

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 = 8675357658240/(1x1544)

LCM = 8675357658240/1544

LCM = 5618754960

Thus, we can understand that the LCM of 420,559,496,193,386 is 5618754960.
