Given numbers are 782,319,642,696,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,319,642,696,791 is 253360520952.
Find LCM of 782,319,642,696,791 with Prime Factorization
| 2 | 782, 319, 642, 696, 791 |
| 3 | 391, 319, 321, 348, 791 |
| 29 | 391, 319, 107, 116, 791 |
| 391, 11, 107, 4, 791 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 391 x 11 x 107 x 4 x 791 = 253360520952
Therefore, the lowest common multiple of 782,319,642,696,791 is 253360520952.
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.
782 x 319 x 642 x 696 x 791 = 88169461291296
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
319 : 1, 11, 29, 319
642 : 1, 2, 3, 6, 107, 214, 321, 642
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,319,642,696,791, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
319:11x 29
642:2x 3x 107
696:2x 2x 2x 3x 29
791:7x 113
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 3x 29 = 348
Therefore, the value for common factors is 348.
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 = 88169461291296/(1x348)
LCM = 88169461291296/348
LCM = 253360520952
Thus, we can understand that the LCM of 782,319,642,696,791 is 253360520952.
