Calculate the LCM of 897,245,165,742

Given numbers are 897,245,165,742

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

The LCM of 897,245,165,742 is 256245990.

Find LCM of 897,245,165,742 with Prime Factorization


3 897, 245, 165, 742
5 299, 245, 55, 742
7 299, 49, 11, 742
299, 7, 11, 106

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

3 x 5 x 7 x 299 x 7 x 11 x 106 = 256245990

Therefore, the lowest common multiple of 897,245,165,742 is 256245990.

LCM Formula to Find Lowest Common Multiple of 897,245,165,742

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.

897 x 245 x 165 x 742 = 26905828950

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.

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

245 : 1, 5, 7, 35, 49, 245

165 : 1, 3, 5, 11, 15, 33, 55, 165

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,245,165,742, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

245:5x 7x 7

165:3x 5x 11

742:2x 7x 53

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

3x 5x 7 = 105

Therefore, the value for common factors is 105.

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 = 26905828950/(1x105)

LCM = 26905828950/105

LCM = 256245990

Thus, we can understand that the LCM of 897,245,165,742 is 256245990.
