Given numbers are 556, 354, 497, 161

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

Apply this formula for all numbers.

Step1:

LCM(556, 354) = 98412

GCD(556, 354) = ( 556 x 354 ) / 98412

= 556 / 354

= 556

Step2:

LCM(2, 497) = 994

GCD(2, 497) = ( 2 x 497 ) / 994

= 2 / 497

= 2

Step3:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

So, Greatest Common Divisor of 556, 354, 497, 161 is 1
