Given numbers are 155, 169, 345, 303
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 169) = 26195
GCD(155, 169) = ( 155 x 169 ) / 26195
= 155 / 169
= 155
Step2:
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
= 1 / 345
= 1
Step3:
LCM(1, 303) = 303
GCD(1, 303) = ( 1 x 303 ) / 303
= 1 / 303
= 1
So, Greatest Common Divisor of 155, 169, 345, 303 is 1
