Given numbers are 933,618,689,390,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 933,618,689,390,861 is 190029045570.
Find LCM of 933,618,689,390,861 with Prime Factorization
| 2 | 933, 618, 689, 390, 861 |
| 3 | 933, 309, 689, 195, 861 |
| 13 | 311, 103, 689, 65, 287 |
| 311, 103, 53, 5, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 311 x 103 x 53 x 5 x 287 = 190029045570
Therefore, the lowest common multiple of 933,618,689,390,861 is 190029045570.
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.
933 x 618 x 689 x 390 x 861 = 133400389990140
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.
933 : 1, 3, 311, 933
618 : 1, 2, 3, 6, 103, 206, 309, 618
689 : 1, 13, 53, 689
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 933,618,689,390,861, is 1.
Now, the common factors can be found like this.
933:3x 311
618:2x 3x 103
689:13x 53
390:2x 3x 5x 13
861:3x 7x 41
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 3x 3x 13 = 702
Therefore, the value for common factors is 702.
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 = 133400389990140/(1x702)
LCM = 133400389990140/702
LCM = 190029045570
Thus, we can understand that the LCM of 933,618,689,390,861 is 190029045570.
