Given numbers are 645, 512, 434, 167

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

Apply this formula for all numbers.

Step1:

LCM(645, 512) = 330240

GCD(645, 512) = ( 645 x 512 ) / 330240

= 645 / 512

= 645

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 167) = 167

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

= 1 / 167

= 1

So, Greatest Common Divisor of 645, 512, 434, 167 is 1
