Given numbers are 403,989,168,542,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,989,168,542,452 is 2050493296488.
Find LCM of 403,989,168,542,452 with Prime Factorization
| 2 | 403, 989, 168, 542, 452 |
| 2 | 403, 989, 84, 271, 226 |
| 403, 989, 42, 271, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 403 x 989 x 42 x 271 x 113 = 2050493296488
Therefore, the lowest common multiple of 403,989,168,542,452 is 2050493296488.
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.
403 x 989 x 168 x 542 x 452 = 16403946371904
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.
403 : 1, 13, 31, 403
989 : 1, 23, 43, 989
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
542 : 1, 2, 271, 542
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,989,168,542,452, is 1.
Now, the common factors can be found like this.
403:13x 31
989:23x 43
168:2x 2x 2x 3x 7
542:2x 271
452:2x 2x 113
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 = 16403946371904/(1x8)
LCM = 16403946371904/8
LCM = 2050493296488
Thus, we can understand that the LCM of 403,989,168,542,452 is 2050493296488.
