Given numbers are 820,821,655,188,112
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,821,655,188,112 is 116060435120.
Find LCM of 820,821,655,188,112 with Prime Factorization
| 2 | 820, 821, 655, 188, 112 |
| 2 | 410, 821, 655, 94, 56 |
| 5 | 205, 821, 655, 47, 28 |
| 41, 821, 131, 47, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 41 x 821 x 131 x 47 x 28 = 116060435120
Therefore, the lowest common multiple of 820,821,655,188,112 is 116060435120.
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 821 x 655 x 188 x 112 = 9284834809600
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
821 : 1, 821
655 : 1, 5, 131, 655
188 : 1, 2, 4, 47, 94, 188
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,821,655,188,112, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
821:821
655:5x 131
188:2x 2x 47
112:2x 2x 2x 2x 7
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 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 9284834809600/(1x80)
LCM = 9284834809600/80
LCM = 116060435120
Thus, we can understand that the LCM of 820,821,655,188,112 is 116060435120.
