GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 395) = 11455
GCD(145, 395) = ( 145 x 395 ) / 11455
= 145 / 395
= 145
Step2:
LCM(5, 981) = 4905
GCD(5, 981) = ( 5 x 981 ) / 4905
= 5 / 981
= 5
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 145, 395, 981, 855 is 1
