Given numbers are 981, 153, 415, 986

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

Apply this formula for all numbers.

Step1:

LCM(981, 153) = 16677

GCD(981, 153) = ( 981 x 153 ) / 16677

= 981 / 153

= 981

Step2:

LCM(9, 415) = 3735

GCD(9, 415) = ( 9 x 415 ) / 3735

= 9 / 415

= 9

Step3:

LCM(1, 986) = 986

GCD(1, 986) = ( 1 x 986 ) / 986

= 1 / 986

= 1

So, Greatest Common Divisor of 981, 153, 415, 986 is 1
