Given numbers are 617, 642, 242, 202

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

Apply this formula for all numbers.

Step1:

LCM(617, 642) = 396114

GCD(617, 642) = ( 617 x 642 ) / 396114

= 617 / 642

= 617

Step2:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

Step3:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

So, Greatest Common Divisor of 617, 642, 242, 202 is 1
