GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(431, 378) = 162918
GCD(431, 378) = ( 431 x 378 ) / 162918
= 431 / 378
= 431
Step2:
LCM(1, 788) = 788
GCD(1, 788) = ( 1 x 788 ) / 788
= 1 / 788
= 1
Step3:
LCM(1, 986) = 986
GCD(1, 986) = ( 1 x 986 ) / 986
= 1 / 986
= 1
So, Greatest Common Divisor of 431, 378, 788, 986 is 1
