The best way to find the least common denominator is through prime factorization. Take the prime factorizations of 10, 5, and 36 and compare them. Take the numbers all three factorizations have in common and raise them to their highest exponents. Hope that helps!

Find the common denominator (Make the bottom number in each fraction the same). In this case, it would be 180. First change 7/10. To make 10=180 you must multiply by 18. Do the same to the numberator. So, this becomes 126/180. For 2/5, multiply the top and bottom by 36, and for 35/36, multiply top and bottom by 5. Your fractions now, all with a common denominator, would be 7/10=126/180, 2/5=72/180, and 35/36=175/180. Hope this helped!

Find the LCD. First you see that 2 of the denominators, 5 and 10 are easy to work with. Your problem is 36. I need to find a number to multiply 36 by that will also be divisible by 5 and 10. I look at the 6 and know that if I multiply it by 5 I will get a number that ends in a zero.....so my LCD is 180 (36 x 5). Now convert them all to equivalent fractions with a denominator of 180. 7/10 = 126/180 .....2/5 = 72/180.......35/36 = 175/180.
