GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 135) = 93015
GCD(689, 135) = ( 689 x 135 ) / 93015
= 689 / 135
= 689
Step2:
LCM(1, 176) = 176
GCD(1, 176) = ( 1 x 176 ) / 176
= 1 / 176
= 1
Step3:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
So, Greatest Common Divisor of 689, 135, 176, 453 is 1
