GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(977, 742) = 724934
GCD(977, 742) = ( 977 x 742 ) / 724934
= 977 / 742
= 977
Step2:
LCM(1, 839) = 839
GCD(1, 839) = ( 1 x 839 ) / 839
= 1 / 839
= 1
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 977, 742, 839, 847 is 1
