Given numbers are 957, 217, 447, 972

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

Apply this formula for all numbers.

Step1:

LCM(957, 217) = 207669

GCD(957, 217) = ( 957 x 217 ) / 207669

= 957 / 217

= 957

Step2:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 957, 217, 447, 972 is 1
