GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 143) = 122551
GCD(857, 143) = ( 857 x 143 ) / 122551
= 857 / 143
= 857
Step2:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
Step3:
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
= 1 / 906
= 1
So, Greatest Common Divisor of 857, 143, 791, 906 is 1
