The least common multiple of two integers is 140, the greatest common divisor is 4, and decimals cannot divide large numbers
140 = 4 × 35, so after removing the greatest common divisor, their product is 35, 35 = 1 × 35 = 5 × 7. Decimals cannot divide large numbers, so there can be neither the smallest 4 nor the largest 140, so it should be 35 = 5 × 7.4 × 5 = 20, 4 × 7 = 28, so these two numbers are 20 and 28. Answer: these two numbers are 20 and 28
