Given numbers are 545,465,620,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,465,620,930 is 202740.
Find LCM of 545,465,620,930 with Prime Factorization
| 2 | 545, 465, 620, 930 |
| 3 | 545, 465, 310, 465 |
| 5 | 545, 155, 310, 155 |
| 31 | 109, 31, 62, 31 |
| 109, 1, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 109 x 1 x 2 x 1 = 202740
Therefore, the lowest common multiple of 545,465,620,930 is 202740.
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 465 x 620 x 930 = 146124855000
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
465 : 1, 3, 5, 15, 31, 93, 155, 465
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,465,620,930, is 5.
Now, the common factors can be found like this.
545:5x 109
465:3x 5x 31
620:2x 2x 5x 31
930:2x 3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 31x 31 = 144150
Therefore, the value for common factors is 144150.
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 = 146124855000/(5x144150)
LCM = 146124855000/720750
LCM = 202740
Thus, we can understand that the LCM of 545,465,620,930 is 202740.
