Given numbers are 943, 464, 247, 642

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

Apply this formula for all numbers.

Step1:

LCM(943, 464) = 437552

GCD(943, 464) = ( 943 x 464 ) / 437552

= 943 / 464

= 943

Step2:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 943, 464, 247, 642 is 1
