Given numbers are 979,169,637,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,169,637,745 is 6039788755.
Find LCM of 979,169,637,745 with Prime Factorization
13 | 979, 169, 637, 745 |
979, 13, 49, 745 |
Multiply the prime numbers at the bottom and the left side.
13 x 979 x 13 x 49 x 745 = 6039788755
Therefore, the lowest common multiple of 979,169,637,745 is 6039788755.
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.
979 x 169 x 637 x 745 = 78517253815
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.
979 : 1, 11, 89, 979
169 : 1, 13, 169
637 : 1, 7, 13, 49, 91, 637
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,169,637,745, is 1.
Now, the common factors can be found like this.
979:11x 89
169:13x 13
637:7x 7x 13
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 78517253815/(1x13)
LCM = 78517253815/13
LCM = 6039788755
Thus, we can understand that the LCM of 979,169,637,745 is 6039788755.
