Given numbers are 855, 747, 857, 461
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 747) = 70965
GCD(855, 747) = ( 855 x 747 ) / 70965
= 855 / 747
= 855
Step2:
LCM(9, 857) = 7713
GCD(9, 857) = ( 9 x 857 ) / 7713
= 9 / 857
= 9
Step3:
LCM(1, 461) = 461
GCD(1, 461) = ( 1 x 461 ) / 461
= 1 / 461
= 1
So, Greatest Common Divisor of 855, 747, 857, 461 is 1
