Given numbers are 443, 646, 153, 475

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

Apply this formula for all numbers.

Step1:

LCM(443, 646) = 286178

GCD(443, 646) = ( 443 x 646 ) / 286178

= 443 / 646

= 443

Step2:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

Step3:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

So, Greatest Common Divisor of 443, 646, 153, 475 is 1
