Given numbers are 556,558,921,997

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

The LCM of 556,558,921,997 is 47480198796.

Find LCM of 556,558,921,997 with Prime Factorization

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

2 x 3 x 278 x 93 x 307 x 997 = 47480198796

Therefore, the lowest common multiple of 556,558,921,997 is 47480198796.

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 558 x 921 x 997 = 284881192776

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

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

921 : 1, 3, 307, 921

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,558,921,997, is 1.

Now, the common factors can be found like this.

556:2x 2x 139

558:2x 3x 3x 31

921:3x 307

997:997

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 284881192776/(1x6)

LCM = 284881192776/6

LCM = 47480198796

Thus, we can understand that the LCM of 556,558,921,997 is 47480198796.
