Given numbers are 223, 643, 780, 619

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

Apply this formula for all numbers.

Step1:

LCM(223, 643) = 143389

GCD(223, 643) = ( 223 x 643 ) / 143389

= 223 / 643

= 223

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

= 1 / 619

= 1

So, Greatest Common Divisor of 223, 643, 780, 619 is 1
