Given numbers are 720,195,829,829
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,195,829,829 is 7759440.
Find LCM of 720,195,829,829 with Prime Factorization
| 3 | 720, 195, 829, 829 |
| 5 | 240, 65, 829, 829 |
| 829 | 48, 13, 829, 829 |
| 48, 13, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 829 x 48 x 13 x 1 x 1 = 7759440
Therefore, the lowest common multiple of 720,195,829,829 is 7759440.
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.
720 x 195 x 829 x 829 = 96488636400
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.
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
195 : 1, 3, 5, 13, 15, 39, 65, 195
829 : 1, 829
829 : 1, 829
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,195,829,829, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
195:3x 5x 13
829:829
829:829
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 829 = 12435
Therefore, the value for common factors is 12435.
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 = 96488636400/(1x12435)
LCM = 96488636400/12435
LCM = 7759440
Thus, we can understand that the LCM of 720,195,829,829 is 7759440.
