Given numbers are 220, 668, 664, 993

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

Apply this formula for all numbers.

Step1:

LCM(220, 668) = 36740

GCD(220, 668) = ( 220 x 668 ) / 36740

= 220 / 668

= 220

Step2:

LCM(4, 664) = 664

GCD(4, 664) = ( 4 x 664 ) / 664

= 4 / 664

= 4

Step3:

LCM(4, 993) = 3972

GCD(4, 993) = ( 4 x 993 ) / 3972

= 4 / 993

= 4

So, Greatest Common Divisor of 220, 668, 664, 993 is 1
