Given numbers are 338,535,806,784,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,535,806,784,861 is 270285877680.
Find LCM of 338,535,806,784,861 with Prime Factorization
| 2 | 338, 535, 806, 784, 861 |
| 7 | 169, 535, 403, 392, 861 |
| 13 | 169, 535, 403, 56, 123 |
| 13, 535, 31, 56, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 13 x 535 x 31 x 56 x 123 = 270285877680
Therefore, the lowest common multiple of 338,535,806,784,861 is 270285877680.
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.
338 x 535 x 806 x 784 x 861 = 98384059475520
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.
338 : 1, 2, 13, 26, 169, 338
535 : 1, 5, 107, 535
806 : 1, 2, 13, 26, 31, 62, 403, 806
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
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 338,535,806,784,861, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
535:5x 107
806:2x 13x 31
784:2x 2x 2x 2x 7x 7
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 2x 7x 13 = 364
Therefore, the value for common factors is 364.
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 = 98384059475520/(1x364)
LCM = 98384059475520/364
LCM = 270285877680
Thus, we can understand that the LCM of 338,535,806,784,861 is 270285877680.
