Given numbers are 238,991,553,978,853
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,991,553,978,853 is 7772050129494.
Find LCM of 238,991,553,978,853 with Prime Factorization
| 2 | 238, 991, 553, 978, 853 |
| 7 | 119, 991, 553, 489, 853 |
| 17, 991, 79, 489, 853 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 991 x 79 x 489 x 853 = 7772050129494
Therefore, the lowest common multiple of 238,991,553,978,853 is 7772050129494.
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.
238 x 991 x 553 x 978 x 853 = 108808701812916
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
991 : 1, 991
553 : 1, 7, 79, 553
978 : 1, 2, 3, 6, 163, 326, 489, 978
853 : 1, 853
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,991,553,978,853, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
991:991
553:7x 79
978:2x 3x 163
853:853
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 108808701812916/(1x14)
LCM = 108808701812916/14
LCM = 7772050129494
Thus, we can understand that the LCM of 238,991,553,978,853 is 7772050129494.
