Given numbers are 697,720,972,867
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,720,972,867 is 230344560.
Find LCM of 697,720,972,867 with Prime Factorization
| 2 | 697, 720, 972, 867 |
| 2 | 697, 360, 486, 867 |
| 3 | 697, 180, 243, 867 |
| 3 | 697, 60, 81, 289 |
| 17 | 697, 20, 27, 289 |
| 41, 20, 27, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 41 x 20 x 27 x 17 = 230344560
Therefore, the lowest common multiple of 697,720,972,867 is 230344560.
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.
697 x 720 x 972 x 867 = 422912612160
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.
697 : 1, 17, 41, 697
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,720,972,867, is 1.
Now, the common factors can be found like this.
697:17x 41
720:2x 2x 2x 2x 3x 3x 5
972:2x 2x 3x 3x 3x 3x 3
867:3x 17x 17
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 3x 17 = 1836
Therefore, the value for common factors is 1836.
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 = 422912612160/(1x1836)
LCM = 422912612160/1836
LCM = 230344560
Thus, we can understand that the LCM of 697,720,972,867 is 230344560.
