Find LCM of 991,702,729,954,749 with Prime Factorization
2 | 991, 702, 729, 954, 749 |
3 | 991, 351, 729, 477, 749 |
3 | 991, 117, 243, 159, 749 |
3 | 991, 39, 81, 53, 749 |
991, 13, 27, 53, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 991 x 13 x 27 x 53 x 749 = 745645185558
Therefore, the lowest common multiple of 991,702,729,954,749 is 745645185558.
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.
991 x 702 x 729 x 954 x 749 = 362383560181188
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.
991 : 1, 991
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
729 : 1, 3, 9, 27, 81, 243, 729
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,702,729,954,749, is 1.
Now, the common factors can be found like this.
991:991
702:2x 3x 3x 3x 13
729:3x 3x 3x 3x 3x 3
954:2x 3x 3x 53
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 362383560181188/(1x486)
LCM = 362383560181188/486
LCM = 745645185558
Thus, we can understand that the LCM of 991,702,729,954,749 is 745645185558.
