Given numbers are 750,123,764,398,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 750,123,764,398,408 is 79476819000.
Find LCM of 750,123,764,398,408 with Prime Factorization
| 2 | 750, 123, 764, 398, 408 |
| 2 | 375, 123, 382, 199, 204 |
| 3 | 375, 123, 191, 199, 102 |
| 125, 41, 191, 199, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 125 x 41 x 191 x 199 x 34 = 79476819000
Therefore, the lowest common multiple of 750,123,764,398,408 is 79476819000.
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.
750 x 123 x 764 x 398 x 408 = 11444661936000
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.
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
123 : 1, 3, 41, 123
764 : 1, 2, 4, 191, 382, 764
398 : 1, 2, 199, 398
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 750,123,764,398,408, is 1.
Now, the common factors can be found like this.
750:2x 3x 5x 5x 5
123:3x 41
764:2x 2x 191
398:2x 199
408:2x 2x 2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 11444661936000/(1x144)
LCM = 11444661936000/144
LCM = 79476819000
Thus, we can understand that the LCM of 750,123,764,398,408 is 79476819000.
