A walkthrough with 3 examples about how to find the LCD of multiple fractions. Excerpt: Write each denominator as a product of its prime factors, so: 15=3∙5 and 35=5∙7 List the shared factors each once and any leftover factors each once. For example 15 and 35 share 5 as a factor, so I write 5 once and include the left over factors 3 and 7 in my LCD each once. The LCD is 5∙3∙7=105 Therefore 105 is the smallest number that both 15 and 35 go into as fact
