Given numbers are 654, 287, 985, 108

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

Apply this formula for all numbers.

Step1:

LCM(654, 287) = 187698

GCD(654, 287) = ( 654 x 287 ) / 187698

= 654 / 287

= 654

Step2:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

Step3:

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

= 1 / 108

= 1

So, Greatest Common Divisor of 654, 287, 985, 108 is 1
