Find LCM of 252,905,560,615,842 with Prime Factorization
| 2 | 252, 905, 560, 615, 842 |
| 2 | 126, 905, 280, 615, 421 |
| 3 | 63, 905, 140, 615, 421 |
| 5 | 21, 905, 140, 205, 421 |
| 7 | 21, 181, 28, 41, 421 |
| 3, 181, 4, 41, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 3 x 181 x 4 x 41 x 421 = 15746174640
Therefore, the lowest common multiple of 252,905,560,615,842 is 15746174640.
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.
252 x 905 x 560 x 615 x 842 = 66133933488000
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.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
905 : 1, 5, 181, 905
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
615 : 1, 3, 5, 15, 41, 123, 205, 615
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,905,560,615,842, is 1.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
905:5x 181
560:2x 2x 2x 2x 5x 7
615:3x 5x 41
842:2x 421
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 2x 3x 5x 5x 7 = 4200
Therefore, the value for common factors is 4200.
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 = 66133933488000/(1x4200)
LCM = 66133933488000/4200
LCM = 15746174640
Thus, we can understand that the LCM of 252,905,560,615,842 is 15746174640.
