Given numbers are 890,274,687,689

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

The LCM of 890,274,687,689 is 57714711990.

Find LCM of 890,274,687,689 with Prime Factorization

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

2 x 445 x 137 x 687 x 689 = 57714711990

Therefore, the lowest common multiple of 890,274,687,689 is 57714711990.

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.

890 x 274 x 687 x 689 = 115429423980

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

274 : 1, 2, 137, 274

687 : 1, 3, 229, 687

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,274,687,689, is 1.

Now, the common factors can be found like this.

890:2x 5x 89

274:2x 137

687:3x 229

689:13x 53

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

2 = 2

Therefore, the value for common factors is 2.

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 = 115429423980/(1x2)

LCM = 115429423980/2

LCM = 57714711990

Thus, we can understand that the LCM of 890,274,687,689 is 57714711990.
