Given numbers are 406, 245, 446, 758
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(406, 245) = 14210
GCD(406, 245) = ( 406 x 245 ) / 14210
= 406 / 245
= 406
Step2:
LCM(7, 446) = 3122
GCD(7, 446) = ( 7 x 446 ) / 3122
= 7 / 446
= 7
Step3:
LCM(1, 758) = 758
GCD(1, 758) = ( 1 x 758 ) / 758
= 1 / 758
= 1
So, Greatest Common Divisor of 406, 245, 446, 758 is 1
