GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 153) = 2601
GCD(289, 153) = ( 289 x 153 ) / 2601
= 289 / 153
= 289
Step2:
LCM(17, 505) = 8585
GCD(17, 505) = ( 17 x 505 ) / 8585
= 17 / 505
= 17
Step3:
LCM(1, 738) = 738
GCD(1, 738) = ( 1 x 738 ) / 738
= 1 / 738
= 1
So, Greatest Common Divisor of 289, 153, 505, 738 is 1
