Given numbers are 556,278,211,991

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

The LCM of 556,278,211,991 is 116260156.

Find LCM of 556,278,211,991 with Prime Factorization

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

2 x 139 x 2 x 1 x 211 x 991 = 116260156

Therefore, the lowest common multiple of 556,278,211,991 is 116260156.

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 278 x 211 x 991 = 32320323368

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

278 : 1, 2, 139, 278

211 : 1, 211

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,278,211,991, is 1.

Now, the common factors can be found like this.

556:2x 2x 139

278:2x 139

211:211

991:991

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

2x 139 = 278

Therefore, the value for common factors is 278.

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 = 32320323368/(1x278)

LCM = 32320323368/278

LCM = 116260156

Thus, we can understand that the LCM of 556,278,211,991 is 116260156.
