Find LCM of 777,735,793,980,155 with Prime Factorization
| 3 | 777, 735, 793, 980, 155 |
| 5 | 259, 245, 793, 980, 155 |
| 7 | 259, 49, 793, 196, 31 |
| 7 | 37, 7, 793, 28, 31 |
| 37, 1, 793, 4, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 7 x 37 x 1 x 793 x 4 x 31 = 2674138740
Therefore, the lowest common multiple of 777,735,793,980,155 is 2674138740.
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 735 x 793 x 980 x 155 = 68792219086500
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
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
793 : 1, 13, 61, 793
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,735,793,980,155, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
735:3x 5x 7x 7
793:13x 61
980:2x 2x 5x 7x 7
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 7x 7x 7 = 25725
Therefore, the value for common factors is 25725.
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 = 68792219086500/(1x25725)
LCM = 68792219086500/25725
LCM = 2674138740
Thus, we can understand that the LCM of 777,735,793,980,155 is 2674138740.
