GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(677, 998) = 675646
GCD(677, 998) = ( 677 x 998 ) / 675646
= 677 / 998
= 677
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
So, Greatest Common Divisor of 677, 998, 639, 437 is 1
