Given numbers are 545,732,741,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,732,741,686 is 33798595740.
Find LCM of 545,732,741,686 with Prime Factorization
| 2 | 545, 732, 741, 686 |
| 3 | 545, 366, 741, 343 |
| 545, 122, 247, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 545 x 122 x 247 x 343 = 33798595740
Therefore, the lowest common multiple of 545,732,741,686 is 33798595740.
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.
545 x 732 x 741 x 686 = 202791574440
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.
545 : 1, 5, 109, 545
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
741 : 1, 3, 13, 19, 39, 57, 247, 741
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,732,741,686, is 1.
Now, the common factors can be found like this.
545:5x 109
732:2x 2x 3x 61
741:3x 13x 19
686:2x 7x 7x 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 3 = 6
Therefore, the value for common factors is 6.
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 = 202791574440/(1x6)
LCM = 202791574440/6
LCM = 33798595740
Thus, we can understand that the LCM of 545,732,741,686 is 33798595740.
