Given numbers are 425,731,272,838

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

The LCM of 425,731,272,838 is 122515600.

Find LCM of 425,731,272,838 with Prime Factorization

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

2 x 17 x 25 x 43 x 8 x 419 = 122515600

Therefore, the lowest common multiple of 425,731,272,838 is 122515600.

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.

425 x 731 x 272 x 838 = 70814016800

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.

425 : 1, 5, 17, 25, 85, 425

731 : 1, 17, 43, 731

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,731,272,838, is 1.

Now, the common factors can be found like this.

425:5x 5x 17

731:17x 43

272:2x 2x 2x 2x 17

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 17x 17 = 578

Therefore, the value for common factors is 578.

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 = 70814016800/(1x578)

LCM = 70814016800/578

LCM = 122515600

Thus, we can understand that the LCM of 425,731,272,838 is 122515600.
