Given numbers are 459, 165, 690, 769
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(459, 165) = 25245
GCD(459, 165) = ( 459 x 165 ) / 25245
= 459 / 165
= 459
Step2:
LCM(3, 690) = 690
GCD(3, 690) = ( 3 x 690 ) / 690
= 3 / 690
= 3
Step3:
LCM(3, 769) = 2307
GCD(3, 769) = ( 3 x 769 ) / 2307
= 3 / 769
= 3
So, Greatest Common Divisor of 459, 165, 690, 769 is 1
