Given numbers are 770,880,759,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,880,759,305 is 25927440.
Find LCM of 770,880,759,305 with Prime Factorization
| 2 | 770, 880, 759, 305 |
| 5 | 385, 440, 759, 305 |
| 11 | 77, 88, 759, 61 |
| 7, 8, 69, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 7 x 8 x 69 x 61 = 25927440
Therefore, the lowest common multiple of 770,880,759,305 is 25927440.
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.
770 x 880 x 759 x 305 = 156861012000
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
759 : 1, 3, 11, 23, 33, 69, 253, 759
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,880,759,305, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
880:2x 2x 2x 2x 5x 11
759:3x 11x 23
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11x 11 = 6050
Therefore, the value for common factors is 6050.
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 = 156861012000/(1x6050)
LCM = 156861012000/6050
LCM = 25927440
Thus, we can understand that the LCM of 770,880,759,305 is 25927440.
