Given numbers are 788,658,195,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,658,195,247 is 960528660.
Find LCM of 788,658,195,247 with Prime Factorization
| 2 | 788, 658, 195, 247 |
| 13 | 394, 329, 195, 247 |
| 394, 329, 15, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 394 x 329 x 15 x 19 = 960528660
Therefore, the lowest common multiple of 788,658,195,247 is 960528660.
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.
788 x 658 x 195 x 247 = 24973745160
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.
788 : 1, 2, 4, 197, 394, 788
658 : 1, 2, 7, 14, 47, 94, 329, 658
195 : 1, 3, 5, 13, 15, 39, 65, 195
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,658,195,247, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
658:2x 7x 47
195:3x 5x 13
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 24973745160/(1x26)
LCM = 24973745160/26
LCM = 960528660
Thus, we can understand that the LCM of 788,658,195,247 is 960528660.
