Given numbers are 985, 490, 603, 621

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

Apply this formula for all numbers.

Step1:

LCM(985, 490) = 96530

GCD(985, 490) = ( 985 x 490 ) / 96530

= 985 / 490

= 985

Step2:

LCM(5, 603) = 3015

GCD(5, 603) = ( 5 x 603 ) / 3015

= 5 / 603

= 5

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 985, 490, 603, 621 is 1
