GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 784) = 50960
GCD(455, 784) = ( 455 x 784 ) / 50960
= 455 / 784
= 455
Step2:
LCM(7, 973) = 973
GCD(7, 973) = ( 7 x 973 ) / 973
= 7 / 973
= 7
Step3:
LCM(7, 805) = 805
GCD(7, 805) = ( 7 x 805 ) / 805
= 7 / 805
= 7
So, Greatest Common Divisor of 455, 784, 973, 805 is 7
