Given numbers are 215, 780, 997, 591

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

Apply this formula for all numbers.

Step1:

LCM(215, 780) = 33540

GCD(215, 780) = ( 215 x 780 ) / 33540

= 215 / 780

= 215

Step2:

LCM(5, 997) = 4985

GCD(5, 997) = ( 5 x 997 ) / 4985

= 5 / 997

= 5

Step3:

LCM(1, 591) = 591

GCD(1, 591) = ( 1 x 591 ) / 591

= 1 / 591

= 1

So, Greatest Common Divisor of 215, 780, 997, 591 is 1
