Given numbers are 780, 808, 754, 693
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 808) = 157560
GCD(780, 808) = ( 780 x 808 ) / 157560
= 780 / 808
= 780
Step2:
LCM(4, 754) = 1508
GCD(4, 754) = ( 4 x 754 ) / 1508
= 4 / 754
= 4
Step3:
LCM(2, 693) = 1386
GCD(2, 693) = ( 2 x 693 ) / 1386
= 2 / 693
= 2
So, Greatest Common Divisor of 780, 808, 754, 693 is 1
