GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 711) = 74655
GCD(945, 711) = ( 945 x 711 ) / 74655
= 945 / 711
= 945
Step2:
LCM(9, 407) = 3663
GCD(9, 407) = ( 9 x 407 ) / 3663
= 9 / 407
= 9
Step3:
LCM(1, 344) = 344
GCD(1, 344) = ( 1 x 344 ) / 344
= 1 / 344
= 1
So, Greatest Common Divisor of 945, 711, 407, 344 is 1
