Find the largest no: which is a factor of 1080 and 729

• we have to find h.c.f (highest common factor) so
  1080 / 729 remainder is 351
  now 729 / 351 remainder is 27
  now 351 / 27 remainder is zero .
  so ans is "27"

• 1080=3^3*2^3*5
  729=3^6
  ans=3^3=27

• 27 as 729=27*27 and 1080 = 27*5*8

• 27
  since
  729 = 3 x 3 x 3 x 3 x 3 x 3
  1080 = 2 x 2 x 3 x 3 x 3 x 2 x 5
  therefore 27 is the number which is the largest factor

• the product of hcf and LCM is equal to the product of two numbers.
  so 1080*729=hcf*lcm..
  the lcm of 1080 and 729 is 9720.
  so hcf=(1080*729)/9720.
  hcf=81

• there are many way As Mayur explain
  and 1 more easy way is Lcm*Hcf= products of number.
  sourobh do it correct but did a mistake lcm of 1080 and 729 is 29160
