Given numbers are 280, 691, 648, 739

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

Apply this formula for all numbers.

Step1:

LCM(280, 691) = 193480

GCD(280, 691) = ( 280 x 691 ) / 193480

= 280 / 691

= 280

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 739) = 739

GCD(1, 739) = ( 1 x 739 ) / 739

= 1 / 739

= 1

So, Greatest Common Divisor of 280, 691, 648, 739 is 1
