Given numbers are 345, 830, 239, 187
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 830) = 57270
GCD(345, 830) = ( 345 x 830 ) / 57270
= 345 / 830
= 345
Step2:
LCM(5, 239) = 1195
GCD(5, 239) = ( 5 x 239 ) / 1195
= 5 / 239
= 5
Step3:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
So, Greatest Common Divisor of 345, 830, 239, 187 is 1
