Given numbers are 543,630,686,153,488
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,630,686,153,488 is 23176825560.
Find LCM of 543,630,686,153,488 with Prime Factorization
| 2 | 543, 630, 686, 153, 488 |
| 3 | 543, 315, 343, 153, 244 |
| 3 | 181, 105, 343, 51, 244 |
| 7 | 181, 35, 343, 17, 244 |
| 181, 5, 49, 17, 244 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 181 x 5 x 49 x 17 x 244 = 23176825560
Therefore, the lowest common multiple of 543,630,686,153,488 is 23176825560.
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.
543 x 630 x 686 x 153 x 488 = 17521680123360
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.
543 : 1, 3, 181, 543
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
686 : 1, 2, 7, 14, 49, 98, 343, 686
153 : 1, 3, 9, 17, 51, 153
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,630,686,153,488, is 1.
Now, the common factors can be found like this.
543:3x 181
630:2x 3x 3x 5x 7
686:2x 7x 7x 7
153:3x 3x 17
488:2x 2x 2x 61
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 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 17521680123360/(1x756)
LCM = 17521680123360/756
LCM = 23176825560
Thus, we can understand that the LCM of 543,630,686,153,488 is 23176825560.
