Given numbers are 390, 497, 910, 408
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 497) = 193830
GCD(390, 497) = ( 390 x 497 ) / 193830
= 390 / 497
= 390
Step2:
LCM(1, 910) = 910
GCD(1, 910) = ( 1 x 910 ) / 910
= 1 / 910
= 1
Step3:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
So, Greatest Common Divisor of 390, 497, 910, 408 is 1
