Given numbers are 391, 661, 624, 419

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

Apply this formula for all numbers.

Step1:

LCM(391, 661) = 258451

GCD(391, 661) = ( 391 x 661 ) / 258451

= 391 / 661

= 391

Step2:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 391, 661, 624, 419 is 1
