Given numbers are 266, 730, 978, 637

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

Apply this formula for all numbers.

Step1:

LCM(266, 730) = 97090

GCD(266, 730) = ( 266 x 730 ) / 97090

= 266 / 730

= 266

Step2:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

Step3:

LCM(2, 637) = 1274

GCD(2, 637) = ( 2 x 637 ) / 1274

= 2 / 637

= 2

So, Greatest Common Divisor of 266, 730, 978, 637 is 1
