Given numbers are 690, 130, 602, 180

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

Apply this formula for all numbers.

Step1:

LCM(690, 130) = 8970

GCD(690, 130) = ( 690 x 130 ) / 8970

= 690 / 130

= 690

Step2:

LCM(10, 602) = 3010

GCD(10, 602) = ( 10 x 602 ) / 3010

= 10 / 602

= 10

Step3:

LCM(2, 180) = 180

GCD(2, 180) = ( 2 x 180 ) / 180

= 2 / 180

= 2

So, Greatest Common Divisor of 690, 130, 602, 180 is 2
