Find LCM of 420,984,308,822,437 with Prime Factorization
| 2 | 420, 984, 308, 822, 437 |
| 2 | 210, 492, 154, 411, 437 |
| 3 | 105, 246, 77, 411, 437 |
| 7 | 35, 82, 77, 137, 437 |
| 5, 82, 11, 137, 437 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 5 x 82 x 11 x 137 x 437 = 22680771960
Therefore, the lowest common multiple of 420,984,308,822,437 is 22680771960.
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 984 x 308 x 822 x 437 = 45724436271360
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
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
822 : 1, 2, 3, 6, 137, 274, 411, 822
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,984,308,822,437, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
984:2x 2x 2x 3x 41
308:2x 2x 7x 11
822:2x 3x 137
437:19x 23
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 = 45724436271360/(1x2016)
LCM = 45724436271360/2016
LCM = 22680771960
Thus, we can understand that the LCM of 420,984,308,822,437 is 22680771960.
