Given numbers are 646, 156, 84, 983

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

Apply this formula for all numbers.

Step1:

LCM(646, 156) = 50388

GCD(646, 156) = ( 646 x 156 ) / 50388

= 646 / 156

= 646

Step2:

LCM(2, 84) = 84

GCD(2, 84) = ( 2 x 84 ) / 84

= 2 / 84

= 2

Step3:

LCM(2, 983) = 1966

GCD(2, 983) = ( 2 x 983 ) / 1966

= 2 / 983

= 2

So, Greatest Common Divisor of 646, 156, 84, 983 is 1
