Given numbers are 424,840,389,428

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

The LCM of 424,840,389,428 is 1853055960.

Find LCM of 424,840,389,428 with Prime Factorization

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

2 x 2 x 2 x 53 x 105 x 389 x 107 = 1853055960

Therefore, the lowest common multiple of 424,840,389,428 is 1853055960.

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.

424 x 840 x 389 x 428 = 59297790720

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

389 : 1, 389

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,840,389,428, is 1.

Now, the common factors can be found like this.

424:2x 2x 2x 53

840:2x 2x 2x 3x 5x 7

389:389

428:2x 2x 107

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 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 59297790720/(1x32)

LCM = 59297790720/32

LCM = 1853055960

Thus, we can understand that the LCM of 424,840,389,428 is 1853055960.
