Given numbers are 394,665,889,903

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

The LCM of 394,665,889,903 is 4292509830.

Find LCM of 394,665,889,903 with Prime Factorization

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

7 x 394 x 95 x 127 x 129 = 4292509830

Therefore, the lowest common multiple of 394,665,889,903 is 4292509830.

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.

394 x 665 x 889 x 903 = 210332981670

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.

394 : 1, 2, 197, 394

665 : 1, 5, 7, 19, 35, 95, 133, 665

889 : 1, 7, 127, 889

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,665,889,903, is 1.

Now, the common factors can be found like this.

394:2x 197

665:5x 7x 19

889:7x 127

903:3x 7x 43

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 210332981670/(1x49)

LCM = 210332981670/49

LCM = 4292509830

Thus, we can understand that the LCM of 394,665,889,903 is 4292509830.
