Given numbers are 665, 921, 893, 855

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

Apply this formula for all numbers.

Step1:

LCM(665, 921) = 612465

GCD(665, 921) = ( 665 x 921 ) / 612465

= 665 / 921

= 665

Step2:

LCM(1, 893) = 893

GCD(1, 893) = ( 1 x 893 ) / 893

= 1 / 893

= 1

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 665, 921, 893, 855 is 1
