Given numbers are 515, 777, 503, 221

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

Apply this formula for all numbers.

Step1:

LCM(515, 777) = 400155

GCD(515, 777) = ( 515 x 777 ) / 400155

= 515 / 777

= 515

Step2:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 515, 777, 503, 221 is 1
