The LCM of 400,389,683,712,309 is 2922663274800.
Find LCM of 400,389,683,712,309 with Prime Factorization
| 2 | 400, 389, 683, 712, 309 |
| 2 | 200, 389, 683, 356, 309 |
| 2 | 100, 389, 683, 178, 309 |
| 50, 389, 683, 89, 309 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 50 x 389 x 683 x 89 x 309 = 2922663274800
Therefore, the lowest common multiple of 400,389,683,712,309 is 2922663274800.
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.
400 x 389 x 683 x 712 x 309 = 23381306198400
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
389 : 1, 389
683 : 1, 683
712 : 1, 2, 4, 8, 89, 178, 356, 712
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,389,683,712,309, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
389:389
683:683
712:2x 2x 2x 89
309:3x 103
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 2 = 8
Therefore, the value for common factors is 8.
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 = 23381306198400/(1x8)
LCM = 23381306198400/8
LCM = 2922663274800
Thus, we can understand that the LCM of 400,389,683,712,309 is 2922663274800.
