Given numbers are 619, 770, 782, 305

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

Apply this formula for all numbers.

Step1:

LCM(619, 770) = 476630

GCD(619, 770) = ( 619 x 770 ) / 476630

= 619 / 770

= 619

Step2:

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

= 1 / 782

= 1

Step3:

LCM(1, 305) = 305

GCD(1, 305) = ( 1 x 305 ) / 305

= 1 / 305

= 1

So, Greatest Common Divisor of 619, 770, 782, 305 is 1
