Without repeated digits, the answer is 7*6*5*4*3 = 2520
2, 3, 3, 3 and 7.
4*5*5 = 100 if digits can be repeated. 4*4*3 = 48 if not.

(75 + 50 + 3 - 5) × 7 + 1 = 862
are the last TWO digits of 5347. 5, 3, 4, and 7 are all digits of the number 5347.
4*5*5 = 100 if digits can be repeated. 4*4*3 = 48 if not.
120 There are 6 digits in total. The numbers with 3 digits, with all digits distinct from each other, are the permutations of the 6 digits taken 3 at a time, and therefore there are 6*5*4 = 120 of them.
If you mean: -7*(5+3) --6 then it is -56+6 = -50
50 = 5*5*2 105 = 5*7*3 so LCM = 5*5*2*7*3 = 1050 1050 = 21*50 and 10 * 105 The LCM is 1050.
