Given numbers are 961, 645, 357, 239

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

Apply this formula for all numbers.

Step1:

LCM(961, 645) = 619845

GCD(961, 645) = ( 961 x 645 ) / 619845

= 961 / 645

= 961

Step2:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

Step3:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

So, Greatest Common Divisor of 961, 645, 357, 239 is 1
