Find LCM of 420,532,856,822,153 with Prime Factorization
| 2 | 420, 532, 856, 822, 153 |
| 2 | 210, 266, 428, 411, 153 |
| 3 | 105, 133, 214, 411, 153 |
| 7 | 35, 133, 214, 137, 51 |
| 5, 19, 214, 137, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 5 x 19 x 214 x 137 x 51 = 11931839640
Therefore, the lowest common multiple of 420,532,856,822,153 is 11931839640.
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.
420 x 532 x 856 x 822 x 153 = 24054588714240
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
856 : 1, 2, 4, 8, 107, 214, 428, 856
822 : 1, 2, 3, 6, 137, 274, 411, 822
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,532,856,822,153, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
532:2x 2x 7x 19
856:2x 2x 2x 107
822:2x 3x 137
153:3x 3x 17
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 2x 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 24054588714240/(1x2016)
LCM = 24054588714240/2016
LCM = 11931839640
Thus, we can understand that the LCM of 420,532,856,822,153 is 11931839640.
