Calculate the LCM of 123,679,161,897

Given numbers are 123,679,161,897

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

The LCM of 123,679,161,897 is 24971583.

Find LCM of 123,679,161,897 with Prime Factorization


3 123, 679, 161, 897
7 41, 679, 161, 299
23 41, 97, 23, 299
41, 97, 1, 13

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

3 x 7 x 23 x 41 x 97 x 1 x 13 = 24971583

Therefore, the lowest common multiple of 123,679,161,897 is 24971583.

LCM Formula to Find Lowest Common Multiple of 123,679,161,897

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.

123 x 679 x 161 x 897 = 12061274589

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.

123 : 1, 3, 41, 123

679 : 1, 7, 97, 679

161 : 1, 7, 23, 161

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,679,161,897, is 1.

Now, the common factors can be found like this.

123:3x 41

679:7x 97

161:7x 23

897:3x 13x 23

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

3x 7x 23 = 483

Therefore, the value for common factors is 483.

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 = 12061274589/(1x483)

LCM = 12061274589/483

LCM = 24971583

Thus, we can understand that the LCM of 123,679,161,897 is 24971583.
