Given numbers are 991,978,425,244,136
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,978,425,244,136 is 100505832600.
Find LCM of 991,978,425,244,136 with Prime Factorization
2 | 991, 978, 425, 244, 136 |
2 | 991, 489, 425, 122, 68 |
17 | 991, 489, 425, 61, 34 |
991, 489, 25, 61, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 991 x 489 x 25 x 61 x 2 = 100505832600
Therefore, the lowest common multiple of 991,978,425,244,136 is 100505832600.
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.
991 x 978 x 425 x 244 x 136 = 13668793233600
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.
991 : 1, 991
978 : 1, 2, 3, 6, 163, 326, 489, 978
425 : 1, 5, 17, 25, 85, 425
244 : 1, 2, 4, 61, 122, 244
136 : 1, 2, 4, 8, 17, 34, 68, 136
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,978,425,244,136, is 1.
Now, the common factors can be found like this.
991:991
978:2x 3x 163
425:5x 5x 17
244:2x 2x 61
136:2x 2x 2x 17
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 2x 17 = 136
Therefore, the value for common factors is 136.
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 = 13668793233600/(1x136)
LCM = 13668793233600/136
LCM = 100505832600
Thus, we can understand that the LCM of 991,978,425,244,136 is 100505832600.
