Given numbers are 349, 568, 641, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(349, 568) = 198232
GCD(349, 568) = ( 349 x 568 ) / 198232
= 349 / 568
= 349
Step2:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
Step3:
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
= 1 / 161
= 1
So, Greatest Common Divisor of 349, 568, 641, 161 is 1
