Given numbers are 728,293,155,143

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

The LCM of 728,293,155,143 is 363683320.

Find LCM of 728,293,155,143 with Prime Factorization

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

13 x 56 x 293 x 155 x 11 = 363683320

Therefore, the lowest common multiple of 728,293,155,143 is 363683320.

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 293 x 155 x 143 = 4727883160

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

293 : 1, 293

155 : 1, 5, 31, 155

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,293,155,143, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

293:293

155:5x 31

143:11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

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 = 4727883160/(1x13)

LCM = 4727883160/13

LCM = 363683320

Thus, we can understand that the LCM of 728,293,155,143 is 363683320.
