69
Prime factors: 2, 3, 23, 23 Others are combinations of the above, i.e. 2 x 3 = 6 2 x 23 = 46 3 x 23 = 69 2 x 3 x 23 = 138 23 x 23 = 529 2 x 23 x 23 = 1058 3 x 23 x 23 = 1587
621 = 3^3 * 233 x 3 x 3 x 23 = 6213 x 3 x 3 x 23
LCM = 621 prime factorization of 23 = 23 27 = ------3 x 3 x 3 ============ LCM=23 x 3 x 3 x 3 = 621
Prime factors are 2, 2, 3 3, 23 Other factors are combinations of primes, i.e. 2 x 2 = 4 2 x 3 = 6 3 x 3 = 9 2 x 2 x 3 = 12 2 x 3 x 3 = 18 2 x 2 x 3 x 3 = 36 2 x 23 = 46 3 x 23 = 69 2 x 2 x 23 = 92 2 x 3 x 23 = 138 3 x 3 x 23 = 207 2 x 2 x 3 x 23 = 276 2 x 3 x 3 x 23 = 414
2 x 2 x 3 x 3 x 23 22 x 32 x 23
4968 = 2 x 2 x 2 x 3 x 3 x 3 x 23 or 23 x 33 x 23
The answer is 3. 69/X=23 69/23=X=3
345 3 x 115 3 x 5 x 23 345 = 3 x 5 x 23
Since 69 is a factor of 207, it will automatically be the GCF of this problem. But let's do it correctly. 3 x 23 = 69 3 x 3 x 23 = 207 Select the common factors. 3 x 23 = 69, the GCF.
1 x 69 3 x 23
3 x 23 = 69 3 x 3 x 23 = 207 3 x 23 = 69, the GCF
There are two ways to do it with whole numbers: (23) x (1) and (-23) x (-1). If you want more ways to do it, you have to use fractions or decimals, and then there are an infinite number of more ways to do it. Here are a few: 11.5 x 2 = 23 5.75 x 4 = 23 5 x 4.6 = 23 0.5 x 46 = 23 2.3 x 10 = 23 3 x 72/3 = 23 6.9 x 31/3 = 23
