Given numbers are 389,943,616,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,943,616,671 is 13783891352.
Find LCM of 389,943,616,671 with Prime Factorization
11 | 389, 943, 616, 671 |
389, 943, 56, 61 |
Multiply the prime numbers at the bottom and the left side.
11 x 389 x 943 x 56 x 61 = 13783891352
Therefore, the lowest common multiple of 389,943,616,671 is 13783891352.
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.
389 x 943 x 616 x 671 = 151622804872
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.
389 : 1, 389
943 : 1, 23, 41, 943
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,943,616,671, is 1.
Now, the common factors can be found like this.
389:389
943:23x 41
616:2x 2x 2x 7x 11
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 151622804872/(1x11)
LCM = 151622804872/11
LCM = 13783891352
Thus, we can understand that the LCM of 389,943,616,671 is 13783891352.
