Given numbers are 154, 945, 981, 890

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

Apply this formula for all numbers.

Step1:

LCM(154, 945) = 20790

GCD(154, 945) = ( 154 x 945 ) / 20790

= 154 / 945

= 154

Step2:

LCM(7, 981) = 6867

GCD(7, 981) = ( 7 x 981 ) / 6867

= 7 / 981

= 7

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 154, 945, 981, 890 is 1
