Given numbers are 238,410,438,556

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

The LCM of 238,410,438,556 is 2970432780.

Find LCM of 238,410,438,556 with Prime Factorization

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

2 x 119 x 205 x 219 x 278 = 2970432780

Therefore, the lowest common multiple of 238,410,438,556 is 2970432780.

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.

238 x 410 x 438 x 556 = 23763462240

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.

238 : 1, 2, 7, 14, 17, 34, 119, 238

410 : 1, 2, 5, 10, 41, 82, 205, 410

438 : 1, 2, 3, 6, 73, 146, 219, 438

556 : 1, 2, 4, 139, 278, 556

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,410,438,556, is 2.

Now, the common factors can be found like this.

238:2x 7x 17

410:2x 5x 41

438:2x 3x 73

556:2x 2x 139

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 23763462240/(2x4)

LCM = 23763462240/8

LCM = 2970432780

Thus, we can understand that the LCM of 238,410,438,556 is 2970432780.
