Given numbers are 234, 689, 281, 978

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

Apply this formula for all numbers.

Step1:

LCM(234, 689) = 12402

GCD(234, 689) = ( 234 x 689 ) / 12402

= 234 / 689

= 234

Step2:

LCM(13, 281) = 3653

GCD(13, 281) = ( 13 x 281 ) / 3653

= 13 / 281

= 13

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 234, 689, 281, 978 is 1
