Given numbers are 355, 990, 809, 624

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

Apply this formula for all numbers.

Step1:

LCM(355, 990) = 70290

GCD(355, 990) = ( 355 x 990 ) / 70290

= 355 / 990

= 355

Step2:

LCM(5, 809) = 4045

GCD(5, 809) = ( 5 x 809 ) / 4045

= 5 / 809

= 5

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 355, 990, 809, 624 is 1
