GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 170) = 22270
GCD(655, 170) = ( 655 x 170 ) / 22270
= 655 / 170
= 655
Step2:
LCM(5, 981) = 4905
GCD(5, 981) = ( 5 x 981 ) / 4905
= 5 / 981
= 5
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 655, 170, 981, 455 is 1
