GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 791) = 24521
GCD(217, 791) = ( 217 x 791 ) / 24521
= 217 / 791
= 217
Step2:
LCM(7, 272) = 1904
GCD(7, 272) = ( 7 x 272 ) / 1904
= 7 / 272
= 7
Step3:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
So, Greatest Common Divisor of 217, 791, 272, 441 is 1
