Find LCM of 620,403,709,939,996 with Prime Factorization
| 2 | 620, 403, 709, 939, 996 |
| 2 | 310, 403, 709, 939, 498 |
| 3 | 155, 403, 709, 939, 249 |
| 31 | 155, 403, 709, 313, 83 |
| 5, 13, 709, 313, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 5 x 13 x 709 x 313 x 83 = 445374103980
Therefore, the lowest common multiple of 620,403,709,939,996 is 445374103980.
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.
620 x 403 x 709 x 939 x 996 = 165679166680560
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
403 : 1, 13, 31, 403
709 : 1, 709
939 : 1, 3, 313, 939
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,403,709,939,996, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
403:13x 31
709:709
939:3x 313
996:2x 2x 3x 83
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 31 = 372
Therefore, the value for common factors is 372.
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 = 165679166680560/(1x372)
LCM = 165679166680560/372
LCM = 445374103980
Thus, we can understand that the LCM of 620,403,709,939,996 is 445374103980.
