Given numbers are 161, 980, 467, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 980) = 22540
GCD(161, 980) = ( 161 x 980 ) / 22540
= 161 / 980
= 161
Step2:
LCM(7, 467) = 3269
GCD(7, 467) = ( 7 x 467 ) / 3269
= 7 / 467
= 7
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 161, 980, 467, 445 is 1
