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

Apply this formula for all numbers.

Step1:

LCM(281, 538) = 151178

GCD(281, 538) = ( 281 x 538 ) / 151178

= 281 / 538

= 281

Step2:

LCM(1, 78) = 78

GCD(1, 78) = ( 1 x 78 ) / 78

= 1 / 78

= 1

So, Greatest Common Divisor of 281, 538, 78 is 1
