Steps to Calculate GCD of 997, 685, 20, 207 using LCM Formula
Given numbers are 997, 685, 20, 207
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(997, 685) = 682945
GCD(997, 685) = ( 997 x 685 ) / 682945
= 997 / 685
= 997
Step2:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
Step3:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
So, Greatest Common Divisor of 997, 685, 20, 207 is 1
