Given numbers are 620, 940, 858, 993

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

Apply this formula for all numbers.

Step1:

LCM(620, 940) = 29140

GCD(620, 940) = ( 620 x 940 ) / 29140

= 620 / 940

= 620

Step2:

LCM(20, 858) = 8580

GCD(20, 858) = ( 20 x 858 ) / 8580

= 20 / 858

= 20

Step3:

LCM(2, 993) = 1986

GCD(2, 993) = ( 2 x 993 ) / 1986

= 2 / 993

= 2

So, Greatest Common Divisor of 620, 940, 858, 993 is 1
