Given numbers are 390, 418, 981, 712
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 418) = 81510
GCD(390, 418) = ( 390 x 418 ) / 81510
= 390 / 418
= 390
Step2:
LCM(2, 981) = 1962
GCD(2, 981) = ( 2 x 981 ) / 1962
= 2 / 981
= 2
Step3:
LCM(1, 712) = 712
GCD(1, 712) = ( 1 x 712 ) / 712
= 1 / 712
= 1
So, Greatest Common Divisor of 390, 418, 981, 712 is 1
