Given numbers are 291, 102, 945, 289
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(291, 102) = 9894
GCD(291, 102) = ( 291 x 102 ) / 9894
= 291 / 102
= 291
Step2:
LCM(3, 945) = 945
GCD(3, 945) = ( 3 x 945 ) / 945
= 3 / 945
= 3
Step3:
LCM(3, 289) = 867
GCD(3, 289) = ( 3 x 289 ) / 867
= 3 / 289
= 3
So, Greatest Common Divisor of 291, 102, 945, 289 is 1
