Given numbers are 643, 246, 646, 182

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

Apply this formula for all numbers.

Step1:

LCM(643, 246) = 158178

GCD(643, 246) = ( 643 x 246 ) / 158178

= 643 / 246

= 643

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 182) = 182

GCD(1, 182) = ( 1 x 182 ) / 182

= 1 / 182

= 1

So, Greatest Common Divisor of 643, 246, 646, 182 is 1
