Given numbers are 728,186,631,340

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

The LCM of 728,186,631,340 is 3631304040.

Find LCM of 728,186,631,340 with Prime Factorization

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

2 x 2 x 182 x 93 x 631 x 85 = 3631304040

Therefore, the lowest common multiple of 728,186,631,340 is 3631304040.

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.

728 x 186 x 631 x 340 = 29050432320

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

186 : 1, 2, 3, 6, 31, 62, 93, 186

631 : 1, 631

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,186,631,340, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

186:2x 3x 31

631:631

340:2x 2x 5x 17

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 2 = 8

Therefore, the value for common factors is 8.

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 = 29050432320/(1x8)

LCM = 29050432320/8

LCM = 3631304040

Thus, we can understand that the LCM of 728,186,631,340 is 3631304040.
