Given numbers are 643, 639, 935, 949

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

Apply this formula for all numbers.

Step1:

LCM(643, 639) = 410877

GCD(643, 639) = ( 643 x 639 ) / 410877

= 643 / 639

= 643

Step2:

LCM(1, 935) = 935

GCD(1, 935) = ( 1 x 935 ) / 935

= 1 / 935

= 1

Step3:

LCM(1, 949) = 949

GCD(1, 949) = ( 1 x 949 ) / 949

= 1 / 949

= 1

So, Greatest Common Divisor of 643, 639, 935, 949 is 1
