Given numbers are 217,942,628,751

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

The LCM of 217,942,628,751 is 307029828.

Find LCM of 217,942,628,751 with Prime Factorization

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

2 x 157 x 217 x 3 x 2 x 751 = 307029828

Therefore, the lowest common multiple of 217,942,628,751 is 307029828.

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.

217 x 942 x 628 x 751 = 96407365992

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.

217 : 1, 7, 31, 217

942 : 1, 2, 3, 6, 157, 314, 471, 942

628 : 1, 2, 4, 157, 314, 628

751 : 1, 751

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,942,628,751, is 1.

Now, the common factors can be found like this.

217:7x 31

942:2x 3x 157

628:2x 2x 157

751:751

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

2x 157 = 314

Therefore, the value for common factors is 314.

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 = 96407365992/(1x314)

LCM = 96407365992/314

LCM = 307029828

Thus, we can understand that the LCM of 217,942,628,751 is 307029828.
