Given numbers are 289, 788, 355, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 788) = 227732
GCD(289, 788) = ( 289 x 788 ) / 227732
= 289 / 788
= 289
Step2:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
Step3:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
So, Greatest Common Divisor of 289, 788, 355, 407 is 1
