GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 147) = 37779
GCD(771, 147) = ( 771 x 147 ) / 37779
= 771 / 147
= 771
Step2:
LCM(3, 439) = 1317
GCD(3, 439) = ( 3 x 439 ) / 1317
= 3 / 439
= 3
Step3:
LCM(1, 997) = 997
GCD(1, 997) = ( 1 x 997 ) / 997
= 1 / 997
= 1
So, Greatest Common Divisor of 771, 147, 439, 997 is 1
