Given numbers are 661, 397, 136, 547

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

Apply this formula for all numbers.

Step1:

LCM(661, 397) = 262417

GCD(661, 397) = ( 661 x 397 ) / 262417

= 661 / 397

= 661

Step2:

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

= 1 / 136

= 1

Step3:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1

So, Greatest Common Divisor of 661, 397, 136, 547 is 1
