GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(230, 638) = 73370
GCD(230, 638) = ( 230 x 638 ) / 73370
= 230 / 638
= 230
Step2:
LCM(2, 963) = 1926
GCD(2, 963) = ( 2 x 963 ) / 1926
= 2 / 963
= 2
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 230, 638, 963, 981 is 1
