Find LCM of 693,643,364,865,360 with Prime Factorization
| 2 | 693, 643, 364, 865, 360 |
| 2 | 693, 643, 182, 865, 180 |
| 3 | 693, 643, 91, 865, 90 |
| 3 | 231, 643, 91, 865, 30 |
| 5 | 77, 643, 91, 865, 10 |
| 7 | 77, 643, 91, 173, 2 |
| 11, 643, 13, 173, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 11 x 643 x 13 x 173 x 2 = 40086086040
Therefore, the lowest common multiple of 693,643,364,865,360 is 40086086040.
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.
693 x 643 x 364 x 865 x 360 = 50508468410400
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
643 : 1, 643
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
865 : 1, 5, 173, 865
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,643,364,865,360, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
643:643
364:2x 2x 7x 13
865:5x 173
360:2x 2x 2x 3x 3x 5
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 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 50508468410400/(1x1260)
LCM = 50508468410400/1260
LCM = 40086086040
Thus, we can understand that the LCM of 693,643,364,865,360 is 40086086040.
