Given numbers are 770,187,578,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,187,578,180 is 4005540.
Find LCM of 770,187,578,180 with Prime Factorization
| 2 | 770, 187, 578, 180 |
| 5 | 385, 187, 289, 90 |
| 11 | 77, 187, 289, 18 |
| 17 | 7, 17, 289, 18 |
| 7, 1, 17, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 17 x 7 x 1 x 17 x 18 = 4005540
Therefore, the lowest common multiple of 770,187,578,180 is 4005540.
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 187 x 578 x 180 = 14980719600
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
187 : 1, 11, 17, 187
578 : 1, 2, 17, 34, 289, 578
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,187,578,180, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
187:11x 17
578:2x 17x 17
180:2x 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 5x 11x 17 = 3740
Therefore, the value for common factors is 3740.
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 = 14980719600/(1x3740)
LCM = 14980719600/3740
LCM = 4005540
Thus, we can understand that the LCM of 770,187,578,180 is 4005540.
