Steps to Calculate GCD of 85, 97, 63, 49 using LCM Formula

Given numbers are 85, 97, 63, 49

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

Apply this formula for all numbers.

Step1:

LCM(85, 97) = 8245

GCD(85, 97) = ( 85 x 97 ) / 8245

= 85 / 97

= 85


Step2:

LCM(1, 63) = 63

GCD(1, 63) = ( 1 x 63 ) / 63

= 1 / 63

= 1


Step3:

LCM(1, 49) = 49

GCD(1, 49) = ( 1 x 49 ) / 49

= 1 / 49

= 1


So, Greatest Common Divisor of 85, 97, 63, 49 is 1
