Given numbers are 749,834,840,732
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,834,840,732 is 762092520.
Find LCM of 749,834,840,732 with Prime Factorization
| 2 | 749, 834, 840, 732 |
| 2 | 749, 417, 420, 366 |
| 3 | 749, 417, 210, 183 |
| 7 | 749, 139, 70, 61 |
| 107, 139, 10, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 107 x 139 x 10 x 61 = 762092520
Therefore, the lowest common multiple of 749,834,840,732 is 762092520.
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.
749 x 834 x 840 x 732 = 384094630080
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.
749 : 1, 7, 107, 749
834 : 1, 2, 3, 6, 139, 278, 417, 834
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,834,840,732, is 1.
Now, the common factors can be found like this.
749:7x 107
834:2x 3x 139
840:2x 2x 2x 3x 5x 7
732:2x 2x 3x 61
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 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 384094630080/(1x504)
LCM = 384094630080/504
LCM = 762092520
Thus, we can understand that the LCM of 749,834,840,732 is 762092520.
