Given numbers are 838,403,406,203

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

The LCM of 838,403,406,203 is 68555942.

Find LCM of 838,403,406,203 with Prime Factorization

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

2 x 7 x 29 x 419 x 403 x 1 x 1 = 68555942

Therefore, the lowest common multiple of 838,403,406,203 is 68555942.

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.

838 x 403 x 406 x 203 = 27833712452

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.

838 : 1, 2, 419, 838

403 : 1, 13, 31, 403

406 : 1, 2, 7, 14, 29, 58, 203, 406

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,403,406,203, is 1.

Now, the common factors can be found like this.

838:2x 419

403:13x 31

406:2x 7x 29

203:7x 29

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

2x 7x 29 = 406

Therefore, the value for common factors is 406.

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 = 27833712452/(1x406)

LCM = 27833712452/406

LCM = 68555942

Thus, we can understand that the LCM of 838,403,406,203 is 68555942.
