Find LCM of 727,690,144,512,142 with Prime Factorization
| 2 | 727, 690, 144, 512, 142 |
| 2 | 727, 345, 72, 256, 71 |
| 2 | 727, 345, 36, 128, 71 |
| 2 | 727, 345, 18, 64, 71 |
| 3 | 727, 345, 9, 32, 71 |
| 727, 115, 3, 32, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 727 x 115 x 3 x 32 x 71 = 27352880640
Therefore, the lowest common multiple of 727,690,144,512,142 is 27352880640.
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.
727 x 690 x 144 x 512 x 142 = 5251753082880
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.
727 : 1, 727
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,690,144,512,142, is 1.
Now, the common factors can be found like this.
727:727
690:2x 3x 5x 23
144:2x 2x 2x 2x 3x 3
512:2x 2x 2x 2x 2x 2x 2x 2x 2
142:2x 71
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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 5251753082880/(1x192)
LCM = 5251753082880/192
LCM = 27352880640
Thus, we can understand that the LCM of 727,690,144,512,142 is 27352880640.
