Steps to Calculate GCD of 170, 991, 916, 239 using LCM Formula
Given numbers are 170, 991, 916, 239
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(170, 991) = 168470
GCD(170, 991) = ( 170 x 991 ) / 168470
= 170 / 991
= 170
Step2:
LCM(1, 916) = 916
GCD(1, 916) = ( 1 x 916 ) / 916
= 1 / 916
= 1
Step3:
LCM(1, 239) = 239
GCD(1, 239) = ( 1 x 239 ) / 239
= 1 / 239
= 1
So, Greatest Common Divisor of 170, 991, 916, 239 is 1
