Given numbers are 405, 126, 602, 836
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 126) = 5670
GCD(405, 126) = ( 405 x 126 ) / 5670
= 405 / 126
= 405
Step2:
LCM(9, 602) = 5418
GCD(9, 602) = ( 9 x 602 ) / 5418
= 9 / 602
= 9
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 405, 126, 602, 836 is 1
