Given numbers are 791, 630, 578, 693
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 630) = 71190
GCD(791, 630) = ( 791 x 630 ) / 71190
= 791 / 630
= 791
Step2:
LCM(7, 578) = 4046
GCD(7, 578) = ( 7 x 578 ) / 4046
= 7 / 578
= 7
Step3:
LCM(1, 693) = 693
GCD(1, 693) = ( 1 x 693 ) / 693
= 1 / 693
= 1
So, Greatest Common Divisor of 791, 630, 578, 693 is 1
