The LCM of 821,932,817,430,116 is 90646100980.
Find LCM of 821,932,817,430,116 with Prime Factorization
| 2 | 821, 932, 817, 430, 116 |
| 2 | 821, 466, 817, 215, 58 |
| 43 | 821, 233, 817, 215, 29 |
| 821, 233, 19, 5, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 821 x 233 x 19 x 5 x 29 = 90646100980
Therefore, the lowest common multiple of 821,932,817,430,116 is 90646100980.
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.
821 x 932 x 817 x 430 x 116 = 31182258737120
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.
821 : 1, 821
932 : 1, 2, 4, 233, 466, 932
817 : 1, 19, 43, 817
430 : 1, 2, 5, 10, 43, 86, 215, 430
116 : 1, 2, 4, 29, 58, 116
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,932,817,430,116, is 1.
Now, the common factors can be found like this.
821:821
932:2x 2x 233
817:19x 43
430:2x 5x 43
116:2x 2x 29
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 43 = 344
Therefore, the value for common factors is 344.
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 = 31182258737120/(1x344)
LCM = 31182258737120/344
LCM = 90646100980
Thus, we can understand that the LCM of 821,932,817,430,116 is 90646100980.
