Calculate the LCM of 720,260,390,334

Given numbers are 720,260,390,334

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

The LCM of 720,260,390,334 is 1563120.

Find LCM of 720,260,390,334 with Prime Factorization


2 720, 260, 390, 334
2 360, 130, 195, 167
3 180, 65, 195, 167
5 60, 65, 65, 167
13 12, 13, 13, 167
12, 1, 1, 167

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

2 x 2 x 3 x 5 x 13 x 12 x 1 x 1 x 167 = 1563120

Therefore, the lowest common multiple of 720,260,390,334 is 1563120.

LCM Formula to Find Lowest Common Multiple of 720,260,390,334

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 260 x 390 x 334 = 24384672000

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

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

334 : 1, 2, 167, 334

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,260,390,334, is 2.

Now, the common factors can be found like this.

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

260:2x 2x 5x 13

390:2x 3x 5x 13

334:2x 167

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 3x 5x 5x 13 = 7800

Therefore, the value for common factors is 7800.

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 = 24384672000/(2x7800)

LCM = 24384672000/15600

LCM = 1563120

Thus, we can understand that the LCM of 720,260,390,334 is 1563120.
