Given numbers are 478, 406, 537, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 406) = 97034
GCD(478, 406) = ( 478 x 406 ) / 97034
= 478 / 406
= 478
Step2:
LCM(2, 537) = 1074
GCD(2, 537) = ( 2 x 537 ) / 1074
= 2 / 537
= 2
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 478, 406, 537, 247 is 1
