Given numbers are 786,623,655,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,623,655,634 is 776139630.
Find LCM of 786,623,655,634 with Prime Factorization
| 2 | 786, 623, 655, 634 |
| 131 | 393, 623, 655, 317 |
| 3, 623, 5, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 3 x 623 x 5 x 317 = 776139630
Therefore, the lowest common multiple of 786,623,655,634 is 776139630.
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 623 x 655 x 634 = 203348583060
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
623 : 1, 7, 89, 623
655 : 1, 5, 131, 655
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,623,655,634, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
623:7x 89
655:5x 131
634:2x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 131 = 262
Therefore, the value for common factors is 262.
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 = 203348583060/(1x262)
LCM = 203348583060/262
LCM = 776139630
Thus, we can understand that the LCM of 786,623,655,634 is 776139630.
