Given numbers are 772, 748, 830, 390

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

Apply this formula for all numbers.

Step1:

LCM(772, 748) = 144364

GCD(772, 748) = ( 772 x 748 ) / 144364

= 772 / 748

= 772

Step2:

LCM(4, 830) = 1660

GCD(4, 830) = ( 4 x 830 ) / 1660

= 4 / 830

= 4

Step3:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

So, Greatest Common Divisor of 772, 748, 830, 390 is 2
