Given numbers are 403,978,540,327,994

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

The LCM of 403,978,540,327,994 is 1921627906380.

Find LCM of 403,978,540,327,994 with Prime Factorization

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

2 x 3 x 403 x 163 x 90 x 109 x 497 = 1921627906380

Therefore, the lowest common multiple of 403,978,540,327,994 is 1921627906380.

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.

403 x 978 x 540 x 327 x 994 = 69178604629680

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.

403 : 1, 13, 31, 403

978 : 1, 2, 3, 6, 163, 326, 489, 978

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

327 : 1, 3, 109, 327

994 : 1, 2, 7, 14, 71, 142, 497, 994

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,978,540,327,994, is 1.

Now, the common factors can be found like this.

403:13x 31

978:2x 3x 163

540:2x 2x 3x 3x 3x 5

327:3x 109

994:2x 7x 71

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 69178604629680/(1x36)

LCM = 69178604629680/36

LCM = 1921627906380

Thus, we can understand that the LCM of 403,978,540,327,994 is 1921627906380.
