Given numbers are 945, 279, 247, 738

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

Apply this formula for all numbers.

Step1:

LCM(945, 279) = 29295

GCD(945, 279) = ( 945 x 279 ) / 29295

= 945 / 279

= 945

Step2:

LCM(9, 247) = 2223

GCD(9, 247) = ( 9 x 247 ) / 2223

= 9 / 247

= 9

Step3:

LCM(1, 738) = 738

GCD(1, 738) = ( 1 x 738 ) / 738

= 1 / 738

= 1

So, Greatest Common Divisor of 945, 279, 247, 738 is 1
