Given numbers are 551, 931, 156, 981

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

Apply this formula for all numbers.

Step1:

LCM(551, 931) = 26999

GCD(551, 931) = ( 551 x 931 ) / 26999

= 551 / 931

= 551

Step2:

LCM(19, 156) = 2964

GCD(19, 156) = ( 19 x 156 ) / 2964

= 19 / 156

= 19

Step3:

LCM(1, 981) = 981

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

= 1 / 981

= 1

So, Greatest Common Divisor of 551, 931, 156, 981 is 1
