Given numbers are 646, 344, 822, 871

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

Apply this formula for all numbers.

Step1:

LCM(646, 344) = 111112

GCD(646, 344) = ( 646 x 344 ) / 111112

= 646 / 344

= 646

Step2:

LCM(2, 822) = 822

GCD(2, 822) = ( 2 x 822 ) / 822

= 2 / 822

= 2

Step3:

LCM(2, 871) = 1742

GCD(2, 871) = ( 2 x 871 ) / 1742

= 2 / 871

= 2

So, Greatest Common Divisor of 646, 344, 822, 871 is 1
