Find LCM of 620,261,957,248 with Prime Factorization
| 2 | 620, 261, 957, 248 |
| 2 | 310, 261, 957, 124 |
| 3 | 155, 261, 957, 62 |
| 29 | 155, 87, 319, 62 |
| 31 | 155, 3, 11, 62 |
| 5, 3, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 29 x 31 x 5 x 3 x 11 x 2 = 3560040
Therefore, the lowest common multiple of 620,261,957,248 is 3560040.
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 261 x 957 x 248 = 38405711520
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
261 : 1, 3, 9, 29, 87, 261
957 : 1, 3, 11, 29, 33, 87, 319, 957
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,261,957,248, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
261:3x 3x 29
957:3x 11x 29
248:2x 2x 2x 31
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 29x 31 = 10788
Therefore, the value for common factors is 10788.
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 = 38405711520/(1x10788)
LCM = 38405711520/10788
LCM = 3560040
Thus, we can understand that the LCM of 620,261,957,248 is 3560040.
