Given numbers are 770,880,856,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,880,856,474 is 156211440.
Find LCM of 770,880,856,474 with Prime Factorization
| 2 | 770, 880, 856, 474 |
| 2 | 385, 440, 428, 237 |
| 2 | 385, 220, 214, 237 |
| 5 | 385, 110, 107, 237 |
| 11 | 77, 22, 107, 237 |
| 7, 2, 107, 237 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 7 x 2 x 107 x 237 = 156211440
Therefore, the lowest common multiple of 770,880,856,474 is 156211440.
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 856 x 474 = 274932134400
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
856 : 1, 2, 4, 8, 107, 214, 428, 856
474 : 1, 2, 3, 6, 79, 158, 237, 474
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,880,856,474, is 2.
Now, the common factors can be found like this.
770:2x 5x 7x 11
880:2x 2x 2x 2x 5x 11
856:2x 2x 2x 107
474:2x 3x 79
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 2x 5x 11 = 880
Therefore, the value for common factors is 880.
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 = 274932134400/(2x880)
LCM = 274932134400/1760
LCM = 156211440
Thus, we can understand that the LCM of 770,880,856,474 is 156211440.
