Given numbers are 972, 371, 97, 639

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

Apply this formula for all numbers.

Step1:

LCM(972, 371) = 360612

GCD(972, 371) = ( 972 x 371 ) / 360612

= 972 / 371

= 972

Step2:

LCM(1, 97) = 97

GCD(1, 97) = ( 1 x 97 ) / 97

= 1 / 97

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 972, 371, 97, 639 is 1
