Given numbers are 791,507,803,649,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,507,803,649,423 is 2678990122809.
Find LCM of 791,507,803,649,423 with Prime Factorization
| 3 | 791, 507, 803, 649, 423 |
| 11 | 791, 169, 803, 649, 141 |
| 791, 169, 73, 59, 141 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 791 x 169 x 73 x 59 x 141 = 2678990122809
Therefore, the lowest common multiple of 791,507,803,649,423 is 2678990122809.
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.
791 x 507 x 803 x 649 x 423 = 88406674052697
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.
791 : 1, 7, 113, 791
507 : 1, 3, 13, 39, 169, 507
803 : 1, 11, 73, 803
649 : 1, 11, 59, 649
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,507,803,649,423, is 1.
Now, the common factors can be found like this.
791:7x 113
507:3x 13x 13
803:11x 73
649:11x 59
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 88406674052697/(1x33)
LCM = 88406674052697/33
LCM = 2678990122809
Thus, we can understand that the LCM of 791,507,803,649,423 is 2678990122809.
