Given numbers are 690, 477, 87, 166

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(690, 477) = 109710

GCD(690, 477) = ( 690 x 477 ) / 109710

= 690 / 477

= 690

Step2:

LCM(3, 87) = 87

GCD(3, 87) = ( 3 x 87 ) / 87

= 3 / 87

= 3

Step3:

LCM(3, 166) = 498

GCD(3, 166) = ( 3 x 166 ) / 498

= 3 / 166

= 3

So, Greatest Common Divisor of 690, 477, 87, 166 is 1
