Given numbers are 623,308,539,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 623,308,539,782 is 75026644.
Find LCM of 623,308,539,782 with Prime Factorization
| 2 | 623, 308, 539, 782 |
| 7 | 623, 154, 539, 391 |
| 11 | 89, 22, 77, 391 |
| 89, 2, 7, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 89 x 2 x 7 x 391 = 75026644
Therefore, the lowest common multiple of 623,308,539,782 is 75026644.
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.
623 x 308 x 539 x 782 = 80878722232
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.
623 : 1, 7, 89, 623
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
539 : 1, 7, 11, 49, 77, 539
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,308,539,782, is 1.
Now, the common factors can be found like this.
623:7x 89
308:2x 2x 7x 11
539:7x 7x 11
782:2x 17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 11 = 1078
Therefore, the value for common factors is 1078.
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 = 80878722232/(1x1078)
LCM = 80878722232/1078
LCM = 75026644
Thus, we can understand that the LCM of 623,308,539,782 is 75026644.
