Given numbers are 556,254,242,121

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

The LCM of 556,254,242,121 is 8544052.

Find LCM of 556,254,242,121 with Prime Factorization

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

2 x 11 x 11 x 278 x 127 x 1 x 1 = 8544052

Therefore, the lowest common multiple of 556,254,242,121 is 8544052.

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.

556 x 254 x 242 x 121 = 4135321168

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.

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

254 : 1, 2, 127, 254

242 : 1, 2, 11, 22, 121, 242

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,254,242,121, is 1.

Now, the common factors can be found like this.

556:2x 2x 139

254:2x 127

242:2x 11x 11

121:11x 11

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 11x 11 = 484

Therefore, the value for common factors is 484.

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 = 4135321168/(1x484)

LCM = 4135321168/484

LCM = 8544052

Thus, we can understand that the LCM of 556,254,242,121 is 8544052.
