GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 962) = 378066
GCD(786, 962) = ( 786 x 962 ) / 378066
= 786 / 962
= 786
Step2:
LCM(2, 981) = 1962
GCD(2, 981) = ( 2 x 981 ) / 1962
= 2 / 981
= 2
Step3:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
So, Greatest Common Divisor of 786, 962, 981, 790 is 1
