Given numbers are 155, 180, 113, 351
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 180) = 5580
GCD(155, 180) = ( 155 x 180 ) / 5580
= 155 / 180
= 155
Step2:
LCM(5, 113) = 565
GCD(5, 113) = ( 5 x 113 ) / 565
= 5 / 113
= 5
Step3:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
So, Greatest Common Divisor of 155, 180, 113, 351 is 1
