240 = 2x2x2x3x5
10000 = 2x2x2x2x5x5x5x5x5
4500 = 2x2x3x3x5x5x5
HCF = 2x2x5 = 20
(2x2x5) is the longest string of multipliers that appears in all 3 numbers.
670 = 2x5x67
54 = 2x3x3x3
27 = 3x3x3
LCM = 2x2x3x3x3 = 108
(write down the longest string of factors you see.
Look at your other numbers and include any factors not already listed)
