Given numbers are 830, 768, 782, 620

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

Apply this formula for all numbers.

Step1:

LCM(830, 768) = 318720

GCD(830, 768) = ( 830 x 768 ) / 318720

= 830 / 768

= 830

Step2:

LCM(2, 782) = 782

GCD(2, 782) = ( 2 x 782 ) / 782

= 2 / 782

= 2

Step3:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

So, Greatest Common Divisor of 830, 768, 782, 620 is 2
