GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 857) = 670174
GCD(782, 857) = ( 782 x 857 ) / 670174
= 782 / 857
= 782
Step2:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
Step3:
LCM(1, 312) = 312
GCD(1, 312) = ( 1 x 312 ) / 312
= 1 / 312
= 1
So, Greatest Common Divisor of 782, 857, 871, 312 is 1
