Given numbers are 161, 621, 457, 133
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 621) = 4347
GCD(161, 621) = ( 161 x 621 ) / 4347
= 161 / 621
= 161
Step2:
LCM(23, 457) = 10511
GCD(23, 457) = ( 23 x 457 ) / 10511
= 23 / 457
= 23
Step3:
LCM(1, 133) = 133
GCD(1, 133) = ( 1 x 133 ) / 133
= 1 / 133
= 1
So, Greatest Common Divisor of 161, 621, 457, 133 is 1
