Given numbers are 646, 311, 843, 837

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

Apply this formula for all numbers.

Step1:

LCM(646, 311) = 200906

GCD(646, 311) = ( 646 x 311 ) / 200906

= 646 / 311

= 646

Step2:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

Step3:

LCM(1, 837) = 837

GCD(1, 837) = ( 1 x 837 ) / 837

= 1 / 837

= 1

So, Greatest Common Divisor of 646, 311, 843, 837 is 1
