Given numbers are 545,756,801,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,756,801,940 is 1723479660.
Find LCM of 545,756,801,940 with Prime Factorization
| 2 | 545, 756, 801, 940 |
| 2 | 545, 378, 801, 470 |
| 3 | 545, 189, 801, 235 |
| 3 | 545, 63, 267, 235 |
| 5 | 545, 21, 89, 235 |
| 109, 21, 89, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 109 x 21 x 89 x 47 = 1723479660
Therefore, the lowest common multiple of 545,756,801,940 is 1723479660.
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 756 x 801 x 940 = 310226338800
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
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
801 : 1, 3, 9, 89, 267, 801
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,756,801,940, is 1.
Now, the common factors can be found like this.
545:5x 109
756:2x 2x 3x 3x 3x 7
801:3x 3x 89
940:2x 2x 5x 47
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 5 = 180
Therefore, the value for common factors is 180.
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 = 310226338800/(1x180)
LCM = 310226338800/180
LCM = 1723479660
Thus, we can understand that the LCM of 545,756,801,940 is 1723479660.
