Given numbers are 285, 977, 402

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

Apply this formula for all numbers.

Step1:

LCM(285, 977) = 278445

GCD(285, 977) = ( 285 x 977 ) / 278445

= 285 / 977

= 285

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 285, 977, 402 is 1
