Given numbers are 639, 972, 313, 348

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

Apply this formula for all numbers.

Step1:

LCM(639, 972) = 69012

GCD(639, 972) = ( 639 x 972 ) / 69012

= 639 / 972

= 639

Step2:

LCM(9, 313) = 2817

GCD(9, 313) = ( 9 x 313 ) / 2817

= 9 / 313

= 9

Step3:

LCM(1, 348) = 348

GCD(1, 348) = ( 1 x 348 ) / 348

= 1 / 348

= 1

So, Greatest Common Divisor of 639, 972, 313, 348 is 1
