The greatest common factor of 220, 440, and 880 is 220
To find the LCM of 110 and 20, you first need to break them up into their prime factors: 110 = 2x5x11 20 = 2x2x5 The next step is to identify the HCF. In this case the HCF will be 2x5 = 10. To find the LCM you multiply the numbers together and divide by the HCF: 110x20/10 = 220. Thus the LCM of 110 and 20 is 220.
To get multiples of 10, multiply 10 by different whole numbers.Similarly, to get multiples of 11, multiply 11 by different whole numbers. If you want COMMON multiples, get the LEAST common multiple of the two; then multiply this least common multiple by different whole numbers to get additional common multiples.
