28+14=42, But 28 x 14=392, Therefore the answer is NO!
x=28

The answer will depend on the units for 14 x 28. Is that 14 ft x 28 ft or 14 miles x 28 miles, 14 metres x 28 metres? Who knows? Not me!
Combinations of such integers are: 1 x (-28) = 28 2 x (-14) = 28 7 x (-4) = 28 14 x (-2) = 28 (-1) x 28 = 28 (-2) x 14 = 28 (-7) x 4 = 28 (-14) x 2 = 28
28
The partial products of 28 x 14 are 112 and 280. 28 = 8 + 20 ⇒ 28 x 14 = 8 x 14 + 20 x 14 = 112 + 280 14 = 4 + 10 ⇒ 28 x 14 = 28 x 4 + 28 x 10 = 112 + 280 The partial products are the same in the different splits as 28 = 2 x 14. If the numbers had been, say, 17 x 28 then: 28 = 8 + 20 ⇒ 28 x 17 = 8 x 17 + 20 x 17 = 136 + 340 17 = 7 + 10 ⇒ 28 x 17 = 28 x 7 + 28 x 10 = 196 + 280
28 = 1 x 28, 2 x 14, 4 x 7, 7 x 4, 14 x 2, 28 x 1
GCF of 28 42 and 56 is 14.The GCF is 14.(28 = 2 x 14, 42 = 3 x 14, 56 = 4 x 14)To find the GCF, factor the numbers and multiply their common prime factors:28 = 2 x 2 x 742 = 2 x 3 x 756 = 2 x 2 x 2 x 7Common factors are 2 x 7 = 14
14 x 14 = 196Also these: 1 x 196, 2 x 98, 4 x 49, 7 x 28.
1 x 28, 2 x 14, 4 x 7, 7 x 4, 14 x 2, 28 x 1
