GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 950) = 304950
GCD(642, 950) = ( 642 x 950 ) / 304950
= 642 / 950
= 642
Step2:
LCM(2, 396) = 396
GCD(2, 396) = ( 2 x 396 ) / 396
= 2 / 396
= 2
Step3:
LCM(2, 940) = 940
GCD(2, 940) = ( 2 x 940 ) / 940
= 2 / 940
= 2
So, Greatest Common Divisor of 642, 950, 396, 940 is 2
