Steps to Calculate GCD of 257, 318, 797, 165 using LCM Formula
Given numbers are 257, 318, 797, 165
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 318) = 81726
GCD(257, 318) = ( 257 x 318 ) / 81726
= 257 / 318
= 257
Step2:
LCM(1, 797) = 797
GCD(1, 797) = ( 1 x 797 ) / 797
= 1 / 797
= 1
Step3:
LCM(1, 165) = 165
GCD(1, 165) = ( 1 x 165 ) / 165
= 1 / 165
= 1
So, Greatest Common Divisor of 257, 318, 797, 165 is 1
