Given numbers are 838,616,683,147,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,616,683,147,788 is 729291177384.
Find LCM of 838,616,683,147,788 with Prime Factorization
| 2 | 838, 616, 683, 147, 788 |
| 2 | 419, 308, 683, 147, 394 |
| 7 | 419, 154, 683, 147, 197 |
| 419, 22, 683, 21, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 419 x 22 x 683 x 21 x 197 = 729291177384
Therefore, the lowest common multiple of 838,616,683,147,788 is 729291177384.
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.
838 x 616 x 683 x 147 x 788 = 40840305933504
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.
838 : 1, 2, 419, 838
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
683 : 1, 683
147 : 1, 3, 7, 21, 49, 147
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,616,683,147,788, is 1.
Now, the common factors can be found like this.
838:2x 419
616:2x 2x 2x 7x 11
683:683
147:3x 7x 7
788:2x 2x 197
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 7 = 56
Therefore, the value for common factors is 56.
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 = 40840305933504/(1x56)
LCM = 40840305933504/56
LCM = 729291177384
Thus, we can understand that the LCM of 838,616,683,147,788 is 729291177384.
