Given numbers are 789,991,742,664,681

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

The LCM of 789,991,742,664,681 is 43723860887112.

Find LCM of 789,991,742,664,681 with Prime Factorization

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

2 x 3 x 263 x 991 x 371 x 332 x 227 = 43723860887112

Therefore, the lowest common multiple of 789,991,742,664,681 is 43723860887112.

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.

789 x 991 x 742 x 664 x 681 = 262343165322672

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.

789 : 1, 3, 263, 789

991 : 1, 991

742 : 1, 2, 7, 14, 53, 106, 371, 742

664 : 1, 2, 4, 8, 83, 166, 332, 664

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,991,742,664,681, is 1.

Now, the common factors can be found like this.

789:3x 263

991:991

742:2x 7x 53

664:2x 2x 2x 83

681:3x 227

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 = 262343165322672/(1x6)

LCM = 262343165322672/6

LCM = 43723860887112

Thus, we can understand that the LCM of 789,991,742,664,681 is 43723860887112.
