Given numbers are 169, 642, 697, 554

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

Apply this formula for all numbers.

Step1:

LCM(169, 642) = 108498

GCD(169, 642) = ( 169 x 642 ) / 108498

= 169 / 642

= 169

Step2:

LCM(1, 697) = 697

GCD(1, 697) = ( 1 x 697 ) / 697

= 1 / 697

= 1

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 169, 642, 697, 554 is 1
