Given numbers are 945, 249, 692, 981

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

Apply this formula for all numbers.

Step1:

LCM(945, 249) = 78435

GCD(945, 249) = ( 945 x 249 ) / 78435

= 945 / 249

= 945

Step2:

LCM(3, 692) = 2076

GCD(3, 692) = ( 3 x 692 ) / 2076

= 3 / 692

= 3

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 945, 249, 692, 981 is 1
