GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 440) = 219560
GCD(998, 440) = ( 998 x 440 ) / 219560
= 998 / 440
= 998
Step2:
LCM(2, 784) = 784
GCD(2, 784) = ( 2 x 784 ) / 784
= 2 / 784
= 2
Step3:
LCM(2, 178) = 178
GCD(2, 178) = ( 2 x 178 ) / 178
= 2 / 178
= 2
So, Greatest Common Divisor of 998, 440, 784, 178 is 2
