Given numbers are 621, 387, 726, 979

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

Apply this formula for all numbers.

Step1:

LCM(621, 387) = 26703

GCD(621, 387) = ( 621 x 387 ) / 26703

= 621 / 387

= 621

Step2:

LCM(9, 726) = 2178

GCD(9, 726) = ( 9 x 726 ) / 2178

= 9 / 726

= 9

Step3:

LCM(3, 979) = 2937

GCD(3, 979) = ( 3 x 979 ) / 2937

= 3 / 979

= 3

So, Greatest Common Divisor of 621, 387, 726, 979 is 1
