Given numbers are 503,921,940,911,196
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 503,921,940,911,196 is 19438821233580.
Find LCM of 503,921,940,911,196 with Prime Factorization
| 2 | 503, 921, 940, 911, 196 |
| 2 | 503, 921, 470, 911, 98 |
| 503, 921, 235, 911, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 503 x 921 x 235 x 911 x 49 = 19438821233580
Therefore, the lowest common multiple of 503,921,940,911,196 is 19438821233580.
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.
503 x 921 x 940 x 911 x 196 = 77755284934320
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.
503 : 1, 503
921 : 1, 3, 307, 921
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
911 : 1, 911
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 503,921,940,911,196, is 1.
Now, the common factors can be found like this.
503:503
921:3x 307
940:2x 2x 5x 47
911:911
196:2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 77755284934320/(1x4)
LCM = 77755284934320/4
LCM = 19438821233580
Thus, we can understand that the LCM of 503,921,940,911,196 is 19438821233580.
