Given numbers are 159, 981, 765, 578

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

Apply this formula for all numbers.

Step1:

LCM(159, 981) = 51993

GCD(159, 981) = ( 159 x 981 ) / 51993

= 159 / 981

= 159

Step2:

LCM(3, 765) = 765

GCD(3, 765) = ( 3 x 765 ) / 765

= 3 / 765

= 3

Step3:

LCM(3, 578) = 1734

GCD(3, 578) = ( 3 x 578 ) / 1734

= 3 / 578

= 3

So, Greatest Common Divisor of 159, 981, 765, 578 is 1
