Given numbers are 857, 685, 351, 851
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 685) = 587045
GCD(857, 685) = ( 857 x 685 ) / 587045
= 857 / 685
= 857
Step2:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
Step3:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
So, Greatest Common Divisor of 857, 685, 351, 851 is 1
