Given numbers are 786,185,816,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,185,816,942 is 3104794320.
Find LCM of 786,185,816,942 with Prime Factorization
2 | 786, 185, 816, 942 |
3 | 393, 185, 408, 471 |
131, 185, 136, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 131 x 185 x 136 x 157 = 3104794320
Therefore, the lowest common multiple of 786,185,816,942 is 3104794320.
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.
786 x 185 x 816 x 942 = 111772595520
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
185 : 1, 5, 37, 185
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,185,816,942, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
185:5x 37
816:2x 2x 2x 2x 3x 17
942:2x 3x 157
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 3 = 36
Therefore, the value for common factors is 36.
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 = 111772595520/(1x36)
LCM = 111772595520/36
LCM = 3104794320
Thus, we can understand that the LCM of 786,185,816,942 is 3104794320.
