Given numbers are 775, 710, 857, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(775, 710) = 110050
GCD(775, 710) = ( 775 x 710 ) / 110050
= 775 / 710
= 775
Step2:
LCM(5, 857) = 4285
GCD(5, 857) = ( 5 x 857 ) / 4285
= 5 / 857
= 5
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 775, 710, 857, 398 is 1
