Given numbers are 637,721,647,731,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,721,647,731,793 is 1892902085347.
Find LCM of 637,721,647,731,793 with Prime Factorization
7 | 637, 721, 647, 731, 793 |
13 | 91, 103, 647, 731, 793 |
7, 103, 647, 731, 61 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 7 x 103 x 647 x 731 x 61 = 1892902085347
Therefore, the lowest common multiple of 637,721,647,731,793 is 1892902085347.
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.
637 x 721 x 647 x 731 x 793 = 172254089766577
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.
637 : 1, 7, 13, 49, 91, 637
721 : 1, 7, 103, 721
647 : 1, 647
731 : 1, 17, 43, 731
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,721,647,731,793, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
721:7x 103
647:647
731:17x 43
793:13x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13 = 91
Therefore, the value for common factors is 91.
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 = 172254089766577/(1x91)
LCM = 172254089766577/91
LCM = 1892902085347
Thus, we can understand that the LCM of 637,721,647,731,793 is 1892902085347.
