Given numbers are 549,153,103,504,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,153,103,504,645 is 11574039960.
Find LCM of 549,153,103,504,645 with Prime Factorization
| 3 | 549, 153, 103, 504, 645 |
| 3 | 183, 51, 103, 168, 215 |
| 61, 17, 103, 56, 215 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 61 x 17 x 103 x 56 x 215 = 11574039960
Therefore, the lowest common multiple of 549,153,103,504,645 is 11574039960.
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.
549 x 153 x 103 x 504 x 645 = 2812491710280
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.
549 : 1, 3, 9, 61, 183, 549
153 : 1, 3, 9, 17, 51, 153
103 : 1, 103
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,153,103,504,645, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
153:3x 3x 17
103:103
504:2x 2x 2x 3x 3x 7
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 2812491710280/(1x243)
LCM = 2812491710280/243
LCM = 11574039960
Thus, we can understand that the LCM of 549,153,103,504,645 is 11574039960.
