Calculate the LCM of 723,742,442,338

Given numbers are 723,742,442,338

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

The LCM of 723,742,442,338 is 1541266818.

Find LCM of 723,742,442,338 with Prime Factorization


2 723, 742, 442, 338
13 723, 371, 221, 169
723, 371, 17, 13

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

2 x 13 x 723 x 371 x 17 x 13 = 1541266818

Therefore, the lowest common multiple of 723,742,442,338 is 1541266818.

LCM Formula to Find Lowest Common Multiple of 723,742,442,338

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.

723 x 742 x 442 x 338 = 80145874536

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.

723 : 1, 3, 241, 723

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

338 : 1, 2, 13, 26, 169, 338

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,742,442,338, is 1.

Now, the common factors can be found like this.

723:3x 241

742:2x 7x 53

442:2x 13x 17

338:2x 13x 13

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

2x 2x 13 = 52

Therefore, the value for common factors is 52.

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 = 80145874536/(1x52)

LCM = 80145874536/52

LCM = 1541266818

Thus, we can understand that the LCM of 723,742,442,338 is 1541266818.
