GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 749) = 23219
GCD(217, 749) = ( 217 x 749 ) / 23219
= 217 / 749
= 217
Step2:
LCM(7, 242) = 1694
GCD(7, 242) = ( 7 x 242 ) / 1694
= 7 / 242
= 7
Step3:
LCM(1, 484) = 484
GCD(1, 484) = ( 1 x 484 ) / 484
= 1 / 484
= 1
So, Greatest Common Divisor of 217, 749, 242, 484 is 1
