GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 471) = 369264
GCD(784, 471) = ( 784 x 471 ) / 369264
= 784 / 471
= 784
Step2:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
Step3:
LCM(1, 108) = 108
GCD(1, 108) = ( 1 x 108 ) / 108
= 1 / 108
= 1
So, Greatest Common Divisor of 784, 471, 254, 108 is 1
