Factors of 26 - 1, 2, 13, 26 Factors of 54 - 1, 2, 3, 6, 9, 18, 27, 54 HCF = 2
6 cubed or 216.
hcf(324, 512) = 4 324 = 2² x 3⁴ 512 = 2⁹ hcf = 2² = 4
Prime factors of 36 are: 2^2 and 3^2 Prime factors of 144 are: 2^4 and 3^2 Prime factors common to both number are 2^2 and 3^2 which when multiplied equals 36 making it the HCF
The number 6 can be factored into 2 x 3. So 6 cubed can be factored into 2 cubed times 3 cubed. In either case, the result is equal to 216.
HCF = 56 LCM = 8008 616 = 2^3 x 7 x 11 728 = 2^3 x 7 x 13 hcf = 2^3 x 7 = 56 lcm = 2^3 x 7 x 11 x 13 = 8008
1 cubed = 13 = 1x1x1 = 1 2 cubed = 23 = 2x2x2 = 8 3 cubed = 33 = 3x3x3 = 27 4 cubed = 43 = 4x4x4 = 64 5 cubed = 53 = 5x5x5 = 125
156: Hcf of 13 and 39= 13 13*12=156 =156
13 cubed is 13 x 13 x13 or 13^3 and equal to 2,197.
hcf = 15 lcm = 3510 270 = 2 x 33 x 5 195 = 3 x 5 x 13 hcf = 3 x 5 = 15 lcm = 2 x 33 x 5 x 13 = 3510

78 = 2 x 3 x 13 9 = 3 x 3 HCF = 2 x 3 x 3 x 13 = 234
The GCF is 13.
hcf(18, 54, 81) = 9. Using prime factorization: 18 = 2 x 3^2 54 = 2 x 3^3 81 = 3^4 hcf = 3^2 = 9
hcf(90, 168, 192) = 2 90 = 2 x 3² x 5 168 = 2³ x 3 x 7 182 = 2 x 7 x 13 hcf = 2
