Given numbers are 943,690,671,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 943,690,671,161 is 132878130.
Find LCM of 943,690,671,161 with Prime Factorization
| 23 | 943, 690, 671, 161 |
| 41, 30, 671, 7 |
Multiply the prime numbers at the bottom and the left side.
23 x 41 x 30 x 671 x 7 = 132878130
Therefore, the lowest common multiple of 943,690,671,161 is 132878130.
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.
943 x 690 x 671 x 161 = 70292530770
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.
943 : 1, 23, 41, 943
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
671 : 1, 11, 61, 671
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 943,690,671,161, is 1.
Now, the common factors can be found like this.
943:23x 41
690:2x 3x 5x 23
671:11x 61
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23 = 529
Therefore, the value for common factors is 529.
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 = 70292530770/(1x529)
LCM = 70292530770/529
LCM = 132878130
Thus, we can understand that the LCM of 943,690,671,161 is 132878130.
