Given numbers are 661, 528, 521, 786

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

Apply this formula for all numbers.

Step1:

LCM(661, 528) = 349008

GCD(661, 528) = ( 661 x 528 ) / 349008

= 661 / 528

= 661

Step2:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 661, 528, 521, 786 is 1
