Given numbers are 387, 630, 961, 240

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

Apply this formula for all numbers.

Step1:

LCM(387, 630) = 27090

GCD(387, 630) = ( 387 x 630 ) / 27090

= 387 / 630

= 387

Step2:

LCM(9, 961) = 8649

GCD(9, 961) = ( 9 x 961 ) / 8649

= 9 / 961

= 9

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 387, 630, 961, 240 is 1
