Given numbers are 645, 471, 581, 347

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

Apply this formula for all numbers.

Step1:

LCM(645, 471) = 101265

GCD(645, 471) = ( 645 x 471 ) / 101265

= 645 / 471

= 645

Step2:

LCM(3, 581) = 1743

GCD(3, 581) = ( 3 x 581 ) / 1743

= 3 / 581

= 3

Step3:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

So, Greatest Common Divisor of 645, 471, 581, 347 is 1
