Given numbers are 691, 197, 318, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 197) = 136127
GCD(691, 197) = ( 691 x 197 ) / 136127
= 691 / 197
= 691
Step2:
LCM(1, 318) = 318
GCD(1, 318) = ( 1 x 318 ) / 318
= 1 / 318
= 1
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 691, 197, 318, 905 is 1
