Given numbers are 671, 221, 320, 515

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

Apply this formula for all numbers.

Step1:

LCM(671, 221) = 148291

GCD(671, 221) = ( 671 x 221 ) / 148291

= 671 / 221

= 671

Step2:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

Step3:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 671, 221, 320, 515 is 1
