Given numbers are 221, 344, 691, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 344) = 76024
GCD(221, 344) = ( 221 x 344 ) / 76024
= 221 / 344
= 221
Step2:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 221, 344, 691, 785 is 1
