Given numbers are 790, 398, 577, 938
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(790, 398) = 157210
GCD(790, 398) = ( 790 x 398 ) / 157210
= 790 / 398
= 790
Step2:
LCM(2, 577) = 1154
GCD(2, 577) = ( 2 x 577 ) / 1154
= 2 / 577
= 2
Step3:
LCM(1, 938) = 938
GCD(1, 938) = ( 1 x 938 ) / 938
= 1 / 938
= 1
So, Greatest Common Divisor of 790, 398, 577, 938 is 1
