Given numbers are 646, 421, 535, 822

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

Apply this formula for all numbers.

Step1:

LCM(646, 421) = 271966

GCD(646, 421) = ( 646 x 421 ) / 271966

= 646 / 421

= 646

Step2:

LCM(1, 535) = 535

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

= 1 / 535

= 1

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 646, 421, 535, 822 is 1
