The LCM of 768,654,775,690,734 is 547625068800.
Find LCM of 768,654,775,690,734 with Prime Factorization
2 | 768, 654, 775, 690, 734 |
3 | 384, 327, 775, 345, 367 |
5 | 128, 109, 775, 115, 367 |
128, 109, 155, 23, 367 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 128 x 109 x 155 x 23 x 367 = 547625068800
Therefore, the lowest common multiple of 768,654,775,690,734 is 547625068800.
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.
768 x 654 x 775 x 690 x 734 = 197145024768000
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
654 : 1, 2, 3, 6, 109, 218, 327, 654
775 : 1, 5, 25, 31, 155, 775
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
734 : 1, 2, 367, 734
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,654,775,690,734, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
654:2x 3x 109
775:5x 5x 31
690:2x 3x 5x 23
734:2x 367
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 2x 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 197145024768000/(1x360)
LCM = 197145024768000/360
LCM = 547625068800
Thus, we can understand that the LCM of 768,654,775,690,734 is 547625068800.
