Given numbers are 527,989,731,103
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 527,989,731,103 is 53683909.
Find LCM of 527,989,731,103 with Prime Factorization
| 17 | 527, 989, 731, 103 |
| 43 | 31, 989, 43, 103 |
| 31, 23, 1, 103 |
Multiply the prime numbers at the bottom and the left side.
17 x 43 x 31 x 23 x 1 x 103 = 53683909
Therefore, the lowest common multiple of 527,989,731,103 is 53683909.
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.
527 x 989 x 731 x 103 = 39242937479
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.
527 : 1, 17, 31, 527
989 : 1, 23, 43, 989
731 : 1, 17, 43, 731
103 : 1, 103
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 527,989,731,103, is 1.
Now, the common factors can be found like this.
527:17x 31
989:23x 43
731:17x 43
103:103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 43 = 731
Therefore, the value for common factors is 731.
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 = 39242937479/(1x731)
LCM = 39242937479/731
LCM = 53683909
Thus, we can understand that the LCM of 527,989,731,103 is 53683909.
