Given numbers are 786,571,690,494,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,571,690,494,722 is 242218354170.
Find LCM of 786,571,690,494,722 with Prime Factorization
| 2 | 786, 571, 690, 494, 722 |
| 3 | 393, 571, 345, 247, 361 |
| 19 | 131, 571, 115, 247, 361 |
| 131, 571, 115, 13, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 131 x 571 x 115 x 13 x 19 = 242218354170
Therefore, the lowest common multiple of 786,571,690,494,722 is 242218354170.
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.
786 x 571 x 690 x 494 x 722 = 110451569501520
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
571 : 1, 571
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
494 : 1, 2, 13, 19, 26, 38, 247, 494
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,571,690,494,722, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
571:571
690:2x 3x 5x 23
494:2x 13x 19
722:2x 19x 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 2x 2x 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 110451569501520/(1x456)
LCM = 110451569501520/456
LCM = 242218354170
Thus, we can understand that the LCM of 786,571,690,494,722 is 242218354170.
