Given numbers are 987, 921, 431, 620

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

Apply this formula for all numbers.

Step1:

LCM(987, 921) = 303009

GCD(987, 921) = ( 987 x 921 ) / 303009

= 987 / 921

= 987

Step2:

LCM(3, 431) = 1293

GCD(3, 431) = ( 3 x 431 ) / 1293

= 3 / 431

= 3

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 987, 921, 431, 620 is 1
