Calculate the LCM of 720,389,338,152

Given numbers are 720,389,338,152

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

The LCM of 720,389,338,152 is 899336880.

Find LCM of 720,389,338,152 with Prime Factorization


2 720, 389, 338, 152
2 360, 389, 169, 76
2 180, 389, 169, 38
90, 389, 169, 19

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

2 x 2 x 2 x 90 x 389 x 169 x 19 = 899336880

Therefore, the lowest common multiple of 720,389,338,152 is 899336880.

LCM Formula to Find Lowest Common Multiple of 720,389,338,152

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 389 x 338 x 152 = 14389390080

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

389 : 1, 389

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

152 : 1, 2, 4, 8, 19, 38, 76, 152

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,389,338,152, is 1.

Now, the common factors can be found like this.

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

389:389

338:2x 13x 13

152:2x 2x 2x 19

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 2 = 16

Therefore, the value for common factors is 16.

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 = 14389390080/(1x16)

LCM = 14389390080/16

LCM = 899336880

Thus, we can understand that the LCM of 720,389,338,152 is 899336880.
