Given numbers are 887,861,205,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 887,861,205,697 is 64915095.
Find LCM of 887,861,205,697 with Prime Factorization
41 | 887, 861, 205, 697 |
887, 21, 5, 17 |
Multiply the prime numbers at the bottom and the left side.
41 x 887 x 21 x 5 x 17 = 64915095
Therefore, the lowest common multiple of 887,861,205,697 is 64915095.
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.
887 x 861 x 205 x 697 = 109122274695
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.
887 : 1, 887
861 : 1, 3, 7, 21, 41, 123, 287, 861
205 : 1, 5, 41, 205
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 887,861,205,697, is 1.
Now, the common factors can be found like this.
887:887
861:3x 7x 41
205:5x 41
697:17x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
41x 41 = 1681
Therefore, the value for common factors is 1681.
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 = 109122274695/(1x1681)
LCM = 109122274695/1681
LCM = 64915095
Thus, we can understand that the LCM of 887,861,205,697 is 64915095.
