Given numbers are 972, 873, 494, 643

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

Apply this formula for all numbers.

Step1:

LCM(972, 873) = 94284

GCD(972, 873) = ( 972 x 873 ) / 94284

= 972 / 873

= 972

Step2:

LCM(9, 494) = 4446

GCD(9, 494) = ( 9 x 494 ) / 4446

= 9 / 494

= 9

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 972, 873, 494, 643 is 1
