The LCM of 546,621,828,695 is 157100580.
Find LCM of 546,621,828,695 with Prime Factorization
| 2 | 546, 621, 828, 695 |
| 3 | 273, 621, 414, 695 |
| 3 | 91, 207, 138, 695 |
| 23 | 91, 69, 46, 695 |
| 91, 3, 2, 695 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 23 x 91 x 3 x 2 x 695 = 157100580
Therefore, the lowest common multiple of 546,621,828,695 is 157100580.
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.
546 x 621 x 828 x 695 = 195118920360
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
621 : 1, 3, 9, 23, 27, 69, 207, 621
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,621,828,695, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
621:3x 3x 3x 23
828:2x 2x 3x 3x 23
695:5x 139
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 3x 3x 23 = 1242
Therefore, the value for common factors is 1242.
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 = 195118920360/(1x1242)
LCM = 195118920360/1242
LCM = 157100580
Thus, we can understand that the LCM of 546,621,828,695 is 157100580.
