Given numbers are 605, 646, 652, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(605, 646) = 390830
GCD(605, 646) = ( 605 x 646 ) / 390830
= 605 / 646
= 605
Step2:
LCM(1, 652) = 652
GCD(1, 652) = ( 1 x 652 ) / 652
= 1 / 652
= 1
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 605, 646, 652, 545 is 1
