There are six factor pairs: 392 = 1 x 392 392 = 2 x 196 392 = 4 x 98 392 = 7 x 56 392 = 8 x 49 392 = 14 x 28
2 x 2 x 2 x 7 x 7 = 392
7 x 56 = 392
it is a method of estimation used in school e.g 698,656,675,689=700,700,700,700next step is to multiply 700 X 4=2800
If you rounded to the nearest hundred, you could do 7300 x 600, so your estimated guess would be 4,380,000. The actual answer is 4,612,336.

392 56 x 7 = 392
392 = 2 x 2 x 2 x 7 x 7.
2 x 2 x 2 x 7 x 7 = 392
2 x 2 x 2 x 7 x 7 = 392
7 x 56 = 392
98 x 4 = 392
The prime factorization of 392 is 2 x 2 x 2 x 7 x 7 or 23 x 72.392= 2x2x2x7x7
78.4 (just take 392 x 0.20)
