Given numbers are 820,185,627,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,185,627,940 is 894089460.
Find LCM of 820,185,627,940 with Prime Factorization
| 2 | 820, 185, 627, 940 |
| 2 | 410, 185, 627, 470 |
| 5 | 205, 185, 627, 235 |
| 41, 37, 627, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 37 x 627 x 47 = 894089460
Therefore, the lowest common multiple of 820,185,627,940 is 894089460.
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.
820 x 185 x 627 x 940 = 89408946000
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
185 : 1, 5, 37, 185
627 : 1, 3, 11, 19, 33, 57, 209, 627
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,185,627,940, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
185:5x 37
627:3x 11x 19
940:2x 2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 89408946000/(1x100)
LCM = 89408946000/100
LCM = 894089460
Thus, we can understand that the LCM of 820,185,627,940 is 894089460.
