Given numbers are 855, 266, 639, 525

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

Apply this formula for all numbers.

Step1:

LCM(855, 266) = 11970

GCD(855, 266) = ( 855 x 266 ) / 11970

= 855 / 266

= 855

Step2:

LCM(19, 639) = 12141

GCD(19, 639) = ( 19 x 639 ) / 12141

= 19 / 639

= 19

Step3:

LCM(1, 525) = 525

GCD(1, 525) = ( 1 x 525 ) / 525

= 1 / 525

= 1

So, Greatest Common Divisor of 855, 266, 639, 525 is 1
