Calculate the LCM of 720,241,745,872

Given numbers are 720,241,745,872

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

The LCM of 720,241,745,872 is 2818138320.

Find LCM of 720,241,745,872 with Prime Factorization


2 720, 241, 745, 872
2 360, 241, 745, 436
2 180, 241, 745, 218
5 90, 241, 745, 109
18, 241, 149, 109

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

2 x 2 x 2 x 5 x 18 x 241 x 149 x 109 = 2818138320

Therefore, the lowest common multiple of 720,241,745,872 is 2818138320.

LCM Formula to Find Lowest Common Multiple of 720,241,745,872

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.

720 x 241 x 745 x 872 = 112725532800

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

241 : 1, 241

745 : 1, 5, 149, 745

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,241,745,872, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

241:241

745:5x 149

872:2x 2x 2x 109

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 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 112725532800/(1x40)

LCM = 112725532800/40

LCM = 2818138320

Thus, we can understand that the LCM of 720,241,745,872 is 2818138320.
