Given numbers are 162, 687, 307, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(162, 687) = 37098
GCD(162, 687) = ( 162 x 687 ) / 37098
= 162 / 687
= 162
Step2:
LCM(3, 307) = 921
GCD(3, 307) = ( 3 x 307 ) / 921
= 3 / 307
= 3
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 162, 687, 307, 390 is 1
