The LCM of 163,437,978,558 is 39746898.
Find LCM of 163,437,978,558 with Prime Factorization
| 2 | 163, 437, 978, 558 |
| 3 | 163, 437, 489, 279 |
| 163 | 163, 437, 163, 93 |
| 1, 437, 1, 93 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 1 x 437 x 1 x 93 = 39746898
Therefore, the lowest common multiple of 163,437,978,558 is 39746898.
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.
163 x 437 x 978 x 558 = 38872466244
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.
163 : 1, 163
437 : 1, 19, 23, 437
978 : 1, 2, 3, 6, 163, 326, 489, 978
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,437,978,558, is 1.
Now, the common factors can be found like this.
163:163
437:19x 23
978:2x 3x 163
558:2x 3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 163 = 978
Therefore, the value for common factors is 978.
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 = 38872466244/(1x978)
LCM = 38872466244/978
LCM = 39746898
Thus, we can understand that the LCM of 163,437,978,558 is 39746898.
