Given numbers are 643, 461, 242, 167

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

Apply this formula for all numbers.

Step1:

LCM(643, 461) = 296423

GCD(643, 461) = ( 643 x 461 ) / 296423

= 643 / 461

= 643

Step2:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

Step3:

LCM(1, 167) = 167

GCD(1, 167) = ( 1 x 167 ) / 167

= 1 / 167

= 1

So, Greatest Common Divisor of 643, 461, 242, 167 is 1
