Given numbers are 229,822,672,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 229,822,672,420 is 105413280.
Find LCM of 229,822,672,420 with Prime Factorization
| 2 | 229, 822, 672, 420 |
| 2 | 229, 411, 336, 210 |
| 3 | 229, 411, 168, 105 |
| 7 | 229, 137, 56, 35 |
| 229, 137, 8, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 229 x 137 x 8 x 5 = 105413280
Therefore, the lowest common multiple of 229,822,672,420 is 105413280.
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.
229 x 822 x 672 x 420 = 53128293120
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.
229 : 1, 229
822 : 1, 2, 3, 6, 137, 274, 411, 822
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 229,822,672,420, is 1.
Now, the common factors can be found like this.
229:229
822:2x 3x 137
672:2x 2x 2x 2x 2x 3x 7
420:2x 2x 3x 5x 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 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 = 53128293120/(1x504)
LCM = 53128293120/504
LCM = 105413280
Thus, we can understand that the LCM of 229,822,672,420 is 105413280.
