Given numbers are 514, 749, 515, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(514, 749) = 384986
GCD(514, 749) = ( 514 x 749 ) / 384986
= 514 / 749
= 514
Step2:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 514, 749, 515, 129 is 1
