Given numbers are 279, 649, 990, 761

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

Apply this formula for all numbers.

Step1:

LCM(279, 649) = 181071

GCD(279, 649) = ( 279 x 649 ) / 181071

= 279 / 649

= 279

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

= 1 / 761

= 1

So, Greatest Common Divisor of 279, 649, 990, 761 is 1
