Infinite. The first 10 are:
321, 642, 963, 1284, 1605, 1926, 2247, 2568, 2889, 3210 . . .
1 x 620 = 620
2 x 620 = 1240
3 x 620 = 1860
and so on.
Any multiple can be multiplied by 621.
For example, 621*4 = 2484
621 * 6 = 3726
1 x 621, 3 x 207, 9 x 69, 23 x 27 = 621
3 and 23
One fathom is equal to six feet. Therefore, 620 fathoms is equal to 620 x 6 = 3720 feet.
The GCF is 310.
1 x 620, 2 x 310, 4 x 155, 5 x 124, 10 x 62, 20 x 31 = 620
Each of these factor pairs (multiply the numbers in parentheses) equals 620: (1, 620) (2, 310) (4, 155) (5, 124) (10, 62) (20, 31)
1x620
310, 620, 930.
The total number of multiples is infinite. Here are the first 10: 155, 310, 465, 620, 775, 930, 1085, 1240, 1395, 1550 . . .

634 is near the following multiples of 10: 620 630 and 640. Rounding, the nearest is 630.
62, 124, 186, 248, 310, 372, 434, 496, 558, 620, 682, 744, 806, 868, 930 . . .
20, 40, 60, 80, 100... Repeat for five more hundreds ...620, 640, 660, 680, 700
The answer is 620
620
45% of 620= 45% * 620= 0.45 * 620= 279
12% of 620= 12% * 620= 0.12 * 620= 74.4
