The LCM of 873,646,934,136,820 is 215962076520.
Find LCM of 873,646,934,136,820 with Prime Factorization
2 | 873, 646, 934, 136, 820 |
2 | 873, 323, 467, 68, 410 |
17 | 873, 323, 467, 34, 205 |
873, 19, 467, 2, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 873 x 19 x 467 x 2 x 205 = 215962076520
Therefore, the lowest common multiple of 873,646,934,136,820 is 215962076520.
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.
873 x 646 x 934 x 136 x 820 = 58741684813440
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.
873 : 1, 3, 9, 97, 291, 873
646 : 1, 2, 17, 19, 34, 38, 323, 646
934 : 1, 2, 467, 934
136 : 1, 2, 4, 8, 17, 34, 68, 136
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,646,934,136,820, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
646:2x 17x 19
934:2x 467
136:2x 2x 2x 17
820:2x 2x 5x 41
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 17 = 272
Therefore, the value for common factors is 272.
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 = 58741684813440/(1x272)
LCM = 58741684813440/272
LCM = 215962076520
Thus, we can understand that the LCM of 873,646,934,136,820 is 215962076520.
