Given numbers are 397,524,322,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,524,322,786 is 100477524.
Find LCM of 397,524,322,786 with Prime Factorization
| 2 | 397, 524, 322, 786 |
| 131 | 397, 262, 161, 393 |
| 397, 2, 161, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 397 x 2 x 161 x 3 = 100477524
Therefore, the lowest common multiple of 397,524,322,786 is 100477524.
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.
397 x 524 x 322 x 786 = 52650222576
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.
397 : 1, 397
524 : 1, 2, 4, 131, 262, 524
322 : 1, 2, 7, 14, 23, 46, 161, 322
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,524,322,786, is 1.
Now, the common factors can be found like this.
397:397
524:2x 2x 131
322:2x 7x 23
786:2x 3x 131
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 131 = 524
Therefore, the value for common factors is 524.
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 = 52650222576/(1x524)
LCM = 52650222576/524
LCM = 100477524
Thus, we can understand that the LCM of 397,524,322,786 is 100477524.
