Given numbers are 459,938,420,696
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 459,938,420,696 is 249714360.
Find LCM of 459,938,420,696 with Prime Factorization
| 2 | 459, 938, 420, 696 |
| 2 | 459, 469, 210, 348 |
| 3 | 459, 469, 105, 174 |
| 7 | 153, 469, 35, 58 |
| 153, 67, 5, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 153 x 67 x 5 x 58 = 249714360
Therefore, the lowest common multiple of 459,938,420,696 is 249714360.
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.
459 x 938 x 420 x 696 = 125856037440
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
938 : 1, 2, 7, 14, 67, 134, 469, 938
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
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,938,420,696, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
938:2x 7x 67
420:2x 2x 3x 5x 7
696:2x 2x 2x 3x 29
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 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 125856037440/(1x504)
LCM = 125856037440/504
LCM = 249714360
Thus, we can understand that the LCM of 459,938,420,696 is 249714360.
