Steps to Calculate GCD of 27, 90, 51, 97 using LCM Formula

Given numbers are 27, 90, 51, 97

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(27, 90) = 270

GCD(27, 90) = ( 27 x 90 ) / 270

= 27 / 90

= 27


Step2:

LCM(9, 51) = 153

GCD(9, 51) = ( 9 x 51 ) / 153

= 9 / 51

= 9


Step3:

LCM(3, 97) = 291

GCD(3, 97) = ( 3 x 97 ) / 291

= 3 / 97

= 3


So, Greatest Common Divisor of 27, 90, 51, 97 is 1
