Given numbers are 255, 550, 989, 746

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

Apply this formula for all numbers.

Step1:

LCM(255, 550) = 28050

GCD(255, 550) = ( 255 x 550 ) / 28050

= 255 / 550

= 255

Step2:

LCM(5, 989) = 4945

GCD(5, 989) = ( 5 x 989 ) / 4945

= 5 / 989

= 5

Step3:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

So, Greatest Common Divisor of 255, 550, 989, 746 is 1
