Given numbers are 169, 644, 618, 613

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

Apply this formula for all numbers.

Step1:

LCM(169, 644) = 108836

GCD(169, 644) = ( 169 x 644 ) / 108836

= 169 / 644

= 169

Step2:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

Step3:

LCM(1, 613) = 613

GCD(1, 613) = ( 1 x 613 ) / 613

= 1 / 613

= 1

So, Greatest Common Divisor of 169, 644, 618, 613 is 1
