Given numbers are 515, 345, 376, 621

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

Apply this formula for all numbers.

Step1:

LCM(515, 345) = 35535

GCD(515, 345) = ( 515 x 345 ) / 35535

= 515 / 345

= 515

Step2:

LCM(5, 376) = 1880

GCD(5, 376) = ( 5 x 376 ) / 1880

= 5 / 376

= 5

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 515, 345, 376, 621 is 1
