The LCM of 871,231,572,166,646 is 21575990436.
Find LCM of 871,231,572,166,646 with Prime Factorization
2 | 871, 231, 572, 166, 646 |
11 | 871, 231, 286, 83, 323 |
13 | 871, 21, 26, 83, 323 |
67, 21, 2, 83, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 67 x 21 x 2 x 83 x 323 = 21575990436
Therefore, the lowest common multiple of 871,231,572,166,646 is 21575990436.
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.
871 x 231 x 572 x 166 x 646 = 12341466529392
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.
871 : 1, 13, 67, 871
231 : 1, 3, 7, 11, 21, 33, 77, 231
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
166 : 1, 2, 83, 166
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,231,572,166,646, is 1.
Now, the common factors can be found like this.
871:13x 67
231:3x 7x 11
572:2x 2x 11x 13
166:2x 83
646:2x 17x 19
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 11x 13 = 572
Therefore, the value for common factors is 572.
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 = 12341466529392/(1x572)
LCM = 12341466529392/572
LCM = 21575990436
Thus, we can understand that the LCM of 871,231,572,166,646 is 21575990436.
