Find LCM of 777,170,307,861,420 with Prime Factorization
2 | 777, 170, 307, 861, 420 |
3 | 777, 85, 307, 861, 210 |
5 | 259, 85, 307, 287, 70 |
7 | 259, 17, 307, 287, 14 |
37, 17, 307, 41, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 37 x 17 x 307 x 41 x 2 = 3325233660
Therefore, the lowest common multiple of 777,170,307,861,420 is 3325233660.
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.
777 x 170 x 307 x 861 x 420 = 14664280440600
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
170 : 1, 2, 5, 10, 17, 34, 85, 170
307 : 1, 307
861 : 1, 3, 7, 21, 41, 123, 287, 861
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,170,307,861,420, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
170:2x 5x 17
307:307
861:3x 7x 41
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 7x 7 = 4410
Therefore, the value for common factors is 4410.
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 = 14664280440600/(1x4410)
LCM = 14664280440600/4410
LCM = 3325233660
Thus, we can understand that the LCM of 777,170,307,861,420 is 3325233660.
