Given numbers are 643, 810, 125, 535

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

Apply this formula for all numbers.

Step1:

LCM(643, 810) = 520830

GCD(643, 810) = ( 643 x 810 ) / 520830

= 643 / 810

= 643

Step2:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

Step3:

LCM(1, 535) = 535

GCD(1, 535) = ( 1 x 535 ) / 535

= 1 / 535

= 1

So, Greatest Common Divisor of 643, 810, 125, 535 is 1
