Given numbers are 453, 685, 643, 828

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

Apply this formula for all numbers.

Step1:

LCM(453, 685) = 310305

GCD(453, 685) = ( 453 x 685 ) / 310305

= 453 / 685

= 453

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 828) = 828

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

= 1 / 828

= 1

So, Greatest Common Divisor of 453, 685, 643, 828 is 1
