Given numbers are 628,382,394,632
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,382,394,632 is 3733501448.
Find LCM of 628,382,394,632 with Prime Factorization
2 | 628, 382, 394, 632 |
2 | 314, 191, 197, 316 |
157, 191, 197, 158 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 157 x 191 x 197 x 158 = 3733501448
Therefore, the lowest common multiple of 628,382,394,632 is 3733501448.
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.
628 x 382 x 394 x 632 = 59736023168
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.
628 : 1, 2, 4, 157, 314, 628
382 : 1, 2, 191, 382
394 : 1, 2, 197, 394
632 : 1, 2, 4, 8, 79, 158, 316, 632
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,382,394,632, is 2.
Now, the common factors can be found like this.
628:2x 2x 157
382:2x 191
394:2x 197
632:2x 2x 2x 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 2 = 8
Therefore, the value for common factors is 8.
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 = 59736023168/(2x8)
LCM = 59736023168/16
LCM = 3733501448
Thus, we can understand that the LCM of 628,382,394,632 is 3733501448.
