Find LCM of 560,295,620,789,291 with Prime Factorization
| 2 | 560, 295, 620, 789, 291 |
| 2 | 280, 295, 310, 789, 291 |
| 3 | 140, 295, 155, 789, 291 |
| 5 | 140, 295, 155, 263, 97 |
| 28, 59, 31, 263, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 28 x 59 x 31 x 263 x 97 = 78388159920
Therefore, the lowest common multiple of 560,295,620,789,291 is 78388159920.
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.
560 x 295 x 620 x 789 x 291 = 23516447976000
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
295 : 1, 5, 59, 295
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
789 : 1, 3, 263, 789
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,295,620,789,291, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
295:5x 59
620:2x 2x 5x 31
789:3x 263
291:3x 97
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 23516447976000/(1x300)
LCM = 23516447976000/300
LCM = 78388159920
Thus, we can understand that the LCM of 560,295,620,789,291 is 78388159920.
