Given numbers are 648, 885, 982, 172

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

Apply this formula for all numbers.

Step1:

LCM(648, 885) = 191160

GCD(648, 885) = ( 648 x 885 ) / 191160

= 648 / 885

= 648

Step2:

LCM(3, 982) = 2946

GCD(3, 982) = ( 3 x 982 ) / 2946

= 3 / 982

= 3

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 648, 885, 982, 172 is 1
