Given numbers are 491,144,363,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,144,363,822 is 1172060208.
Find LCM of 491,144,363,822 with Prime Factorization
| 2 | 491, 144, 363, 822 |
| 3 | 491, 72, 363, 411 |
| 491, 24, 121, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 491 x 24 x 121 x 137 = 1172060208
Therefore, the lowest common multiple of 491,144,363,822 is 1172060208.
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.
491 x 144 x 363 x 822 = 21097083744
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.
491 : 1, 491
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
363 : 1, 3, 11, 33, 121, 363
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,144,363,822, is 1.
Now, the common factors can be found like this.
491:491
144:2x 2x 2x 2x 3x 3
363:3x 11x 11
822:2x 3x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 21097083744/(1x18)
LCM = 21097083744/18
LCM = 1172060208
Thus, we can understand that the LCM of 491,144,363,822 is 1172060208.
