Given numbers are 778,273,806,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,273,806,774 is 849363606.
Find LCM of 778,273,806,774 with Prime Factorization
| 2 | 778, 273, 806, 774 |
| 3 | 389, 273, 403, 387 |
| 13 | 389, 91, 403, 129 |
| 389, 7, 31, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 389 x 7 x 31 x 129 = 849363606
Therefore, the lowest common multiple of 778,273,806,774 is 849363606.
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.
778 x 273 x 806 x 774 = 132500722536
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.
778 : 1, 2, 389, 778
273 : 1, 3, 7, 13, 21, 39, 91, 273
806 : 1, 2, 13, 26, 31, 62, 403, 806
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,273,806,774, is 1.
Now, the common factors can be found like this.
778:2x 389
273:3x 7x 13
806:2x 13x 31
774:2x 3x 3x 43
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 132500722536/(1x156)
LCM = 132500722536/156
LCM = 849363606
Thus, we can understand that the LCM of 778,273,806,774 is 849363606.
