Given numbers are 202, 690, 163, 425

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

Apply this formula for all numbers.

Step1:

LCM(202, 690) = 69690

GCD(202, 690) = ( 202 x 690 ) / 69690

= 202 / 690

= 202

Step2:

LCM(2, 163) = 326

GCD(2, 163) = ( 2 x 163 ) / 326

= 2 / 163

= 2

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 202, 690, 163, 425 is 1
