Given numbers are 738,665,123,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,665,123,921 is 150666390.
Find LCM of 738,665,123,921 with Prime Factorization
3 | 738, 665, 123, 921 |
41 | 246, 665, 41, 307 |
6, 665, 1, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 6 x 665 x 1 x 307 = 150666390
Therefore, the lowest common multiple of 738,665,123,921 is 150666390.
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.
738 x 665 x 123 x 921 = 55595897910
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
665 : 1, 5, 7, 19, 35, 95, 133, 665
123 : 1, 3, 41, 123
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,665,123,921, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
665:5x 7x 19
123:3x 41
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 41 = 369
Therefore, the value for common factors is 369.
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 = 55595897910/(1x369)
LCM = 55595897910/369
LCM = 150666390
Thus, we can understand that the LCM of 738,665,123,921 is 150666390.
