Given numbers are 643, 563, 43, 828

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

Apply this formula for all numbers.

Step1:

LCM(643, 563) = 362009

GCD(643, 563) = ( 643 x 563 ) / 362009

= 643 / 563

= 643

Step2:

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

= 1 / 43

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 643, 563, 43, 828 is 1
