Given numbers are 616,745,447,838

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

The LCM of 616,745,447,838 is 576862440.

Find LCM of 616,745,447,838 with Prime Factorization

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

2 x 149 x 308 x 5 x 3 x 419 = 576862440

Therefore, the lowest common multiple of 616,745,447,838 is 576862440.

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.

616 x 745 x 447 x 838 = 171905007120

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.

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

745 : 1, 5, 149, 745

447 : 1, 3, 149, 447

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,745,447,838, is 1.

Now, the common factors can be found like this.

616:2x 2x 2x 7x 11

745:5x 149

447:3x 149

838:2x 419

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

2x 149 = 298

Therefore, the value for common factors is 298.

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 = 171905007120/(1x298)

LCM = 171905007120/298

LCM = 576862440

Thus, we can understand that the LCM of 616,745,447,838 is 576862440.
