16 × 27 × 49 is a single number with value 21168.
It requires at least one other number with which it can have COMMON factors. When the OTHER NUMBERS with which it has COMMON factor(s) are known, the factors of THOSE NUMBERS can be found and the COMMON ones listed, and the HIGHEST COMMON FACTOR fount; it will be one of the factors of 21168 which are: 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 16, 18, 21, 24, 27, 28, 36, 42, 48, 49, 54, 56, 63, 72, 84, 98, 108, 112, 126, 144, 147, 168, 189, 196, 216, 252, 294, 336, 378, 392, 432, 441, 504, 588, 756, 784, 882, 1008, 1176, 1323, 1512, 1764, 2352, 2646, 3024, 3528, 5292, 7056, 10584, 21168.

If you meant "What is the HCF of 16 27 and 49", then:
hcf(16, 27, 49) = 1
hcf(16×27×49, 8×2725) = 8×27 = 216 Using prime factorisation: 16×27×49 = 2⁴ × 3³ × 7² 8×27×125 = 2³ × 3³ × 5³ → hcf = 2³ × 3³ = 8×27 = 216
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
The HCF is 5.
the HCF is 6
The HCF is 1
HCF = 14
The HCF of 228 and 240 is 12.
The HCF of 16 & 33 is... 1
HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2 HCF(10, 84) = 2
The HCF is 1.
The HCF is 14.
