Given numbers are 305,981,436,397

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

The LCM of 305,981,436,397 is 475137540.

Find LCM of 305,981,436,397 with Prime Factorization

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

109 x 305 x 9 x 4 x 397 = 475137540

Therefore, the lowest common multiple of 305,981,436,397 is 475137540.

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.

305 x 981 x 436 x 397 = 51789991860

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.

305 : 1, 5, 61, 305

981 : 1, 3, 9, 109, 327, 981

436 : 1, 2, 4, 109, 218, 436

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,981,436,397, is 1.

Now, the common factors can be found like this.

305:5x 61

981:3x 3x 109

436:2x 2x 109

397:397

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

109 = 109

Therefore, the value for common factors is 109.

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 = 51789991860/(1x109)

LCM = 51789991860/109

LCM = 475137540

Thus, we can understand that the LCM of 305,981,436,397 is 475137540.
