Given numbers are 509, 551, 39, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(509, 551) = 280459
GCD(509, 551) = ( 509 x 551 ) / 280459
= 509 / 551
= 509
Step2:
LCM(1, 39) = 39
GCD(1, 39) = ( 1 x 39 ) / 39
= 1 / 39
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 509, 551, 39, 129 is 1
