Factor trees are found to find the LCM. 60 = 30 x 2 = 10 x 3 x 2 = 5 x 2 x 3 x 2 (prime numbers, no further breakdown) 80 = 40 x 2 = 20 x 2 x 2 = 5 x 4 x 2 x 2 = 5 x 2 x 2 x 2 x 2 (prime numbers, no further breakdown) Notice that 5 x 2 x 2 appers in the factor tree for 60 and 80. Times all the factor tree numbers together and cross out 5 x 2 x 2: 3 x 5 x 2 x 2 x 2 x 2 = 240 which is the of 60 and 80 QED.
