Given numbers are 640, 849, 296, 972

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

Apply this formula for all numbers.

Step1:

LCM(640, 849) = 543360

GCD(640, 849) = ( 640 x 849 ) / 543360

= 640 / 849

= 640

Step2:

LCM(1, 296) = 296

GCD(1, 296) = ( 1 x 296 ) / 296

= 1 / 296

= 1

Step3:

LCM(1, 972) = 972

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

= 1 / 972

= 1

So, Greatest Common Divisor of 640, 849, 296, 972 is 1
