Given numbers are 344, 680, 905, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(344, 680) = 29240
GCD(344, 680) = ( 344 x 680 ) / 29240
= 344 / 680
= 344
Step2:
LCM(8, 905) = 7240
GCD(8, 905) = ( 8 x 905 ) / 7240
= 8 / 905
= 8
Step3:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
So, Greatest Common Divisor of 344, 680, 905, 655 is 1
