Given numbers are 111,283,640,450,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,283,640,450,770 is 23220489600.
Find LCM of 111,283,640,450,770 with Prime Factorization
| 2 | 111, 283, 640, 450, 770 |
| 3 | 111, 283, 320, 225, 385 |
| 5 | 37, 283, 320, 75, 385 |
| 37, 283, 64, 15, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 283 x 64 x 15 x 77 = 23220489600
Therefore, the lowest common multiple of 111,283,640,450,770 is 23220489600.
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.
111 x 283 x 640 x 450 x 770 = 6966146880000
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.
111 : 1, 3, 37, 111
283 : 1, 283
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,283,640,450,770, is 1.
Now, the common factors can be found like this.
111:3x 37
283:283
640:2x 2x 2x 2x 2x 2x 2x 5
450:2x 3x 3x 5x 5
770:2x 5x 7x 11
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 6966146880000/(1x300)
LCM = 6966146880000/300
LCM = 23220489600
Thus, we can understand that the LCM of 111,283,640,450,770 is 23220489600.
