Given numbers are 985, 403, 638, 775
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 403) = 396955
GCD(985, 403) = ( 985 x 403 ) / 396955
= 985 / 403
= 985
Step2:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
Step3:
LCM(1, 775) = 775
GCD(1, 775) = ( 1 x 775 ) / 775
= 1 / 775
= 1
So, Greatest Common Divisor of 985, 403, 638, 775 is 1
