Given numbers are 727,388,278,254,780

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

The LCM of 727,388,278,254,780 is 971000087460.

Find LCM of 727,388,278,254,780 with Prime Factorization

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

2 x 2 x 727 x 97 x 139 x 127 x 195 = 971000087460

Therefore, the lowest common multiple of 727,388,278,254,780 is 971000087460.

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.

727 x 388 x 278 x 254 x 780 = 15536001399360

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.

727 : 1, 727

388 : 1, 2, 4, 97, 194, 388

278 : 1, 2, 139, 278

254 : 1, 2, 127, 254

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,388,278,254,780, is 1.

Now, the common factors can be found like this.

727:727

388:2x 2x 97

278:2x 139

254:2x 127

780:2x 2x 3x 5x 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 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 = 15536001399360/(1x16)

LCM = 15536001399360/16

LCM = 971000087460

Thus, we can understand that the LCM of 727,388,278,254,780 is 971000087460.
