Given numbers are 531, 177, 644, 981

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

Apply this formula for all numbers.

Step1:

LCM(531, 177) = 531

GCD(531, 177) = ( 531 x 177 ) / 531

= 531 / 177

= 531

Step2:

LCM(177, 644) = 113988

GCD(177, 644) = ( 177 x 644 ) / 113988

= 177 / 644

= 177

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 531, 177, 644, 981 is 1
