Given numbers are 972,786,396,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,786,396,749 is 1049088348.
Find LCM of 972,786,396,749 with Prime Factorization
| 2 | 972, 786, 396, 749 |
| 2 | 486, 393, 198, 749 |
| 3 | 243, 393, 99, 749 |
| 3 | 81, 131, 33, 749 |
| 27, 131, 11, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 27 x 131 x 11 x 749 = 1049088348
Therefore, the lowest common multiple of 972,786,396,749 is 1049088348.
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.
972 x 786 x 396 x 749 = 226603083168
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
786 : 1, 2, 3, 6, 131, 262, 393, 786
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,786,396,749, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
786:2x 3x 131
396:2x 2x 3x 3x 11
749:7x 107
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 3 = 216
Therefore, the value for common factors is 216.
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 = 226603083168/(1x216)
LCM = 226603083168/216
LCM = 1049088348
Thus, we can understand that the LCM of 972,786,396,749 is 1049088348.
