Given numbers are 555, 250, 853, 821

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

Apply this formula for all numbers.

Step1:

LCM(555, 250) = 27750

GCD(555, 250) = ( 555 x 250 ) / 27750

= 555 / 250

= 555

Step2:

LCM(5, 853) = 4265

GCD(5, 853) = ( 5 x 853 ) / 4265

= 5 / 853

= 5

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 555, 250, 853, 821 is 1
