Given numbers are 103,749,343,973
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,749,343,973 is 525448217.
Find LCM of 103,749,343,973 with Prime Factorization
7 | 103, 749, 343, 973 |
103, 107, 49, 139 |
Multiply the prime numbers at the bottom and the left side.
7 x 103 x 107 x 49 x 139 = 525448217
Therefore, the lowest common multiple of 103,749,343,973 is 525448217.
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.
103 x 749 x 343 x 973 = 25746962633
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.
103 : 1, 103
749 : 1, 7, 107, 749
343 : 1, 7, 49, 343
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,749,343,973, is 1.
Now, the common factors can be found like this.
103:103
749:7x 107
343:7x 7x 7
973:7x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 25746962633/(1x49)
LCM = 25746962633/49
LCM = 525448217
Thus, we can understand that the LCM of 103,749,343,973 is 525448217.
