Given numbers are 388, 972, 471, 140

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

Apply this formula for all numbers.

Step1:

LCM(388, 972) = 94284

GCD(388, 972) = ( 388 x 972 ) / 94284

= 388 / 972

= 388

Step2:

LCM(4, 471) = 1884

GCD(4, 471) = ( 4 x 471 ) / 1884

= 4 / 471

= 4

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 388, 972, 471, 140 is 1
