Given numbers are 647, 322, 299, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 322) = 208334
GCD(647, 322) = ( 647 x 322 ) / 208334
= 647 / 322
= 647
Step2:
LCM(1, 299) = 299
GCD(1, 299) = ( 1 x 299 ) / 299
= 1 / 299
= 1
Step3:
LCM(1, 181) = 181
GCD(1, 181) = ( 1 x 181 ) / 181
= 1 / 181
= 1
So, Greatest Common Divisor of 647, 322, 299, 181 is 1
