Given numbers are 850,806,720,690,357
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,806,720,690,357 is 3970839600.
Find LCM of 850,806,720,690,357 with Prime Factorization
| 2 | 850, 806, 720, 690, 357 |
| 3 | 425, 403, 360, 345, 357 |
| 5 | 425, 403, 120, 115, 119 |
| 17 | 85, 403, 24, 23, 119 |
| 5, 403, 24, 23, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 5 x 403 x 24 x 23 x 7 = 3970839600
Therefore, the lowest common multiple of 850,806,720,690,357 is 3970839600.
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.
850 x 806 x 720 x 690 x 357 = 121507691760000
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
806 : 1, 2, 13, 26, 31, 62, 403, 806
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,806,720,690,357, is 1.
Now, the common factors can be found like this.
850:2x 5x 5x 17
806:2x 13x 31
720:2x 2x 2x 2x 3x 3x 5
690:2x 3x 5x 23
357:3x 7x 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 2x 3x 3x 5x 5x 17 = 30600
Therefore, the value for common factors is 30600.
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 = 121507691760000/(1x30600)
LCM = 121507691760000/30600
LCM = 3970839600
Thus, we can understand that the LCM of 850,806,720,690,357 is 3970839600.
