Steps to Calculate GCD of 97, 90, 71, 85 using LCM Formula

Given numbers are 97, 90, 71, 85

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

Apply this formula for all numbers.

Step1:

LCM(97, 90) = 8730

GCD(97, 90) = ( 97 x 90 ) / 8730

= 97 / 90

= 97


Step2:

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

= 1 / 71

= 1


Step3:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1


So, Greatest Common Divisor of 97, 90, 71, 85 is 1
