Given numbers are 815,853,978,47

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

The LCM of 815,853,978,47 is 196044990.

Find LCM of 815,853,978,47 with Prime Factorization

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

163 x 5 x 853 x 6 x 47 = 196044990

Therefore, the lowest common multiple of 815,853,978,47 is 196044990.

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.

815 x 853 x 978 x 47 = 31955333370

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.

815 : 1, 5, 163, 815

853 : 1, 853

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

47 : 1, 47

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,853,978,47, is 1.

Now, the common factors can be found like this.

815:5x 163

853:853

978:2x 3x 163

47:47

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

163 = 163

Therefore, the value for common factors is 163.

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 = 31955333370/(1x163)

LCM = 31955333370/163

LCM = 196044990

Thus, we can understand that the LCM of 815,853,978,47 is 196044990.
