Given numbers are 356, 136, 861, 169

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

Apply this formula for all numbers.

Step1:

LCM(356, 136) = 12104

GCD(356, 136) = ( 356 x 136 ) / 12104

= 356 / 136

= 356

Step2:

LCM(4, 861) = 3444

GCD(4, 861) = ( 4 x 861 ) / 3444

= 4 / 861

= 4

Step3:

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

= 1 / 169

= 1

So, Greatest Common Divisor of 356, 136, 861, 169 is 1
