Given numbers are 261,186,903,818

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

The LCM of 261,186,903,818 is 1992149838.

Find LCM of 261,186,903,818 with Prime Factorization

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

2 x 3 x 87 x 31 x 301 x 409 = 1992149838

Therefore, the lowest common multiple of 261,186,903,818 is 1992149838.

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.

261 x 186 x 903 x 818 = 35858697084

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.

261 : 1, 3, 9, 29, 87, 261

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

903 : 1, 3, 7, 21, 43, 129, 301, 903

818 : 1, 2, 409, 818

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,186,903,818, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

186:2x 3x 31

903:3x 7x 43

818:2x 409

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 35858697084/(1x18)

LCM = 35858697084/18

LCM = 1992149838

Thus, we can understand that the LCM of 261,186,903,818 is 1992149838.
