Find LCM of 421,560,842,173,504 with Prime Factorization
| 2 | 421, 560, 842, 173, 504 |
| 2 | 421, 280, 421, 173, 252 |
| 2 | 421, 140, 421, 173, 126 |
| 7 | 421, 70, 421, 173, 63 |
| 421 | 421, 10, 421, 173, 9 |
| 1, 10, 1, 173, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 421 x 1 x 10 x 1 x 173 x 9 = 367078320
Therefore, the lowest common multiple of 421,560,842,173,504 is 367078320.
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.
421 x 560 x 842 x 173 x 504 = 17308476944640
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.
421 : 1, 421
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
842 : 1, 2, 421, 842
173 : 1, 173
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,560,842,173,504, is 1.
Now, the common factors can be found like this.
421:421
560:2x 2x 2x 2x 5x 7
842:2x 421
173:173
504:2x 2x 2x 3x 3x 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 2x 2x 2x 7x 421 = 47152
Therefore, the value for common factors is 47152.
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 = 17308476944640/(1x47152)
LCM = 17308476944640/47152
LCM = 367078320
Thus, we can understand that the LCM of 421,560,842,173,504 is 367078320.
