GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 716) = 141052
GCD(788, 716) = ( 788 x 716 ) / 141052
= 788 / 716
= 788
Step2:
LCM(4, 840) = 840
GCD(4, 840) = ( 4 x 840 ) / 840
= 4 / 840
= 4
Step3:
LCM(4, 858) = 1716
GCD(4, 858) = ( 4 x 858 ) / 1716
= 4 / 858
= 4
So, Greatest Common Divisor of 788, 716, 840, 858 is 2
