Given numbers are 102,681,551,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,681,551,638 is 140336394.
Find LCM of 102,681,551,638 with Prime Factorization
2 | 102, 681, 551, 638 |
3 | 51, 681, 551, 319 |
29 | 17, 227, 551, 319 |
17, 227, 19, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 17 x 227 x 19 x 11 = 140336394
Therefore, the lowest common multiple of 102,681,551,638 is 140336394.
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.
102 x 681 x 551 x 638 = 24418532556
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
681 : 1, 3, 227, 681
551 : 1, 19, 29, 551
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,681,551,638, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
681:3x 227
551:19x 29
638:2x 11x 29
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 29 = 174
Therefore, the value for common factors is 174.
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 = 24418532556/(1x174)
LCM = 24418532556/174
LCM = 140336394
Thus, we can understand that the LCM of 102,681,551,638 is 140336394.
