Given numbers are 687, 187, 378, 339
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 187) = 128469
GCD(687, 187) = ( 687 x 187 ) / 128469
= 687 / 187
= 687
Step2:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
Step3:
LCM(1, 339) = 339
GCD(1, 339) = ( 1 x 339 ) / 339
= 1 / 339
= 1
So, Greatest Common Divisor of 687, 187, 378, 339 is 1
