GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 768) = 39168
GCD(153, 768) = ( 153 x 768 ) / 39168
= 153 / 768
= 153
Step2:
LCM(3, 309) = 309
GCD(3, 309) = ( 3 x 309 ) / 309
= 3 / 309
= 3
Step3:
LCM(3, 817) = 2451
GCD(3, 817) = ( 3 x 817 ) / 2451
= 3 / 817
= 3
So, Greatest Common Divisor of 153, 768, 309, 817 is 1
