Given numbers are 543,748,605,611,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,748,605,611,621 is 2825372232540.
Find LCM of 543,748,605,611,621 with Prime Factorization
| 3 | 543, 748, 605, 611, 621 |
| 11 | 181, 748, 605, 611, 207 |
| 181, 68, 55, 611, 207 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 181 x 68 x 55 x 611 x 207 = 2825372232540
Therefore, the lowest common multiple of 543,748,605,611,621 is 2825372232540.
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 748 x 605 x 611 x 621 = 93237283673820
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
605 : 1, 5, 11, 55, 121, 605
611 : 1, 13, 47, 611
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,748,605,611,621, is 1.
Now, the common factors can be found like this.
543:3x 181
748:2x 2x 11x 17
605:5x 11x 11
611:13x 47
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 93237283673820/(1x33)
LCM = 93237283673820/33
LCM = 2825372232540
Thus, we can understand that the LCM of 543,748,605,611,621 is 2825372232540.
