Given numbers are 398, 270, 791, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 270) = 53730
GCD(398, 270) = ( 398 x 270 ) / 53730
= 398 / 270
= 398
Step2:
LCM(2, 791) = 1582
GCD(2, 791) = ( 2 x 791 ) / 1582
= 2 / 791
= 2
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 398, 270, 791, 965 is 1
