Given numbers are 685,158,816,274
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,158,816,274 is 44157840.
Find LCM of 685,158,816,274 with Prime Factorization
2 | 685, 158, 816, 274 |
137 | 685, 79, 408, 137 |
5, 79, 408, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 137 x 5 x 79 x 408 x 1 = 44157840
Therefore, the lowest common multiple of 685,158,816,274 is 44157840.
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.
685 x 158 x 816 x 274 = 24198496320
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.
685 : 1, 5, 137, 685
158 : 1, 2, 79, 158
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
274 : 1, 2, 137, 274
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,158,816,274, is 1.
Now, the common factors can be found like this.
685:5x 137
158:2x 79
816:2x 2x 2x 2x 3x 17
274:2x 137
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 137 = 548
Therefore, the value for common factors is 548.
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 = 24198496320/(1x548)
LCM = 24198496320/548
LCM = 44157840
Thus, we can understand that the LCM of 685,158,816,274 is 44157840.
