Given numbers are 390, 788, 238, 723
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 788) = 153660
GCD(390, 788) = ( 390 x 788 ) / 153660
= 390 / 788
= 390
Step2:
LCM(2, 238) = 238
GCD(2, 238) = ( 2 x 238 ) / 238
= 2 / 238
= 2
Step3:
LCM(2, 723) = 1446
GCD(2, 723) = ( 2 x 723 ) / 1446
= 2 / 723
= 2
So, Greatest Common Divisor of 390, 788, 238, 723 is 1
