Given numbers are 397,681,651,881
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,681,651,881 is 51686040189.
Find LCM of 397,681,651,881 with Prime Factorization
3 | 397, 681, 651, 881 |
397, 227, 217, 881 |
Multiply the prime numbers at the bottom and the left side.
3 x 397 x 227 x 217 x 881 = 51686040189
Therefore, the lowest common multiple of 397,681,651,881 is 51686040189.
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.
397 x 681 x 651 x 881 = 155058120567
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.
397 : 1, 397
681 : 1, 3, 227, 681
651 : 1, 3, 7, 21, 31, 93, 217, 651
881 : 1, 881
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,681,651,881, is 1.
Now, the common factors can be found like this.
397:397
681:3x 227
651:3x 7x 31
881:881
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 155058120567/(1x3)
LCM = 155058120567/3
LCM = 51686040189
Thus, we can understand that the LCM of 397,681,651,881 is 51686040189.
