Given numbers are 154, 847, 978, 159

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

Apply this formula for all numbers.

Step1:

LCM(154, 847) = 1694

GCD(154, 847) = ( 154 x 847 ) / 1694

= 154 / 847

= 154

Step2:

LCM(77, 978) = 75306

GCD(77, 978) = ( 77 x 978 ) / 75306

= 77 / 978

= 77

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 154, 847, 978, 159 is 1
