Given numbers are 154, 221, 293, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 221) = 34034
GCD(154, 221) = ( 154 x 221 ) / 34034
= 154 / 221
= 154
Step2:
LCM(1, 293) = 293
GCD(1, 293) = ( 1 x 293 ) / 293
= 1 / 293
= 1
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 154, 221, 293, 447 is 1
