GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 449) = 99229
GCD(221, 449) = ( 221 x 449 ) / 99229
= 221 / 449
= 221
Step2:
LCM(1, 475) = 475
GCD(1, 475) = ( 1 x 475 ) / 475
= 1 / 475
= 1
Step3:
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
= 1 / 906
= 1
So, Greatest Common Divisor of 221, 449, 475, 906 is 1
