Given numbers are 690, 125, 434, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 125) = 17250
GCD(690, 125) = ( 690 x 125 ) / 17250
= 690 / 125
= 690
Step2:
LCM(5, 434) = 2170
GCD(5, 434) = ( 5 x 434 ) / 2170
= 5 / 434
= 5
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 690, 125, 434, 129 is 1
