Given numbers are 791, 742, 690, 393
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 742) = 83846
GCD(791, 742) = ( 791 x 742 ) / 83846
= 791 / 742
= 791
Step2:
LCM(7, 690) = 4830
GCD(7, 690) = ( 7 x 690 ) / 4830
= 7 / 690
= 7
Step3:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
So, Greatest Common Divisor of 791, 742, 690, 393 is 1
