Given numbers are 220, 440, 781, 893

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

Apply this formula for all numbers.

Step1:

LCM(220, 440) = 440

GCD(220, 440) = ( 220 x 440 ) / 440

= 220 / 440

= 220

Step2:

LCM(220, 781) = 15620

GCD(220, 781) = ( 220 x 781 ) / 15620

= 220 / 781

= 220

Step3:

LCM(11, 893) = 9823

GCD(11, 893) = ( 11 x 893 ) / 9823

= 11 / 893

= 11

So, Greatest Common Divisor of 220, 440, 781, 893 is 1
