GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 708) = 276828
GCD(782, 708) = ( 782 x 708 ) / 276828
= 782 / 708
= 782
Step2:
LCM(2, 436) = 436
GCD(2, 436) = ( 2 x 436 ) / 436
= 2 / 436
= 2
Step3:
LCM(2, 399) = 798
GCD(2, 399) = ( 2 x 399 ) / 798
= 2 / 399
= 2
So, Greatest Common Divisor of 782, 708, 436, 399 is 1
