Given numbers are 657,792,394,948
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,792,394,948 is 899790408.
Find LCM of 657,792,394,948 with Prime Factorization
| 2 | 657, 792, 394, 948 |
| 2 | 657, 396, 197, 474 |
| 3 | 657, 198, 197, 237 |
| 3 | 219, 66, 197, 79 |
| 73, 22, 197, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 73 x 22 x 197 x 79 = 899790408
Therefore, the lowest common multiple of 657,792,394,948 is 899790408.
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.
657 x 792 x 394 x 948 = 194354728128
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.
657 : 1, 3, 9, 73, 219, 657
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
394 : 1, 2, 197, 394
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,792,394,948, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
792:2x 2x 2x 3x 3x 11
394:2x 197
948:2x 2x 3x 79
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 = 194354728128/(1x216)
LCM = 194354728128/216
LCM = 899790408
Thus, we can understand that the LCM of 657,792,394,948 is 899790408.
