Calculate the LCM of 742,288,484

Given numbers are 742,288,484

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

The LCM of 742,288,484 is 12928608.

Find LCM of 742,288,484 with Prime Factorization


2 742, 288, 484
2 371, 144, 242
371, 72, 121

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

2 x 2 x 371 x 72 x 121 = 12928608

Therefore, the lowest common multiple of 742,288,484 is 12928608.

LCM Formula to Find Lowest Common Multiple of 742,288,484

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.

742 x 288 x 484 = 103428864

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.

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

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

484 : 1, 2, 4, 11, 22, 44, 121, 242, 484

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,288,484, is 2.

Now, the common factors can be found like this.

742:2x 7x 53

288:2x 2x 2x 2x 2x 3x 3

484:2x 2x 11x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 103428864/(2x4)

LCM = 103428864/8

LCM = 12928608

Thus, we can understand that the LCM of 742,288,484 is 12928608.
