GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 976) = 623664
GCD(639, 976) = ( 639 x 976 ) / 623664
= 639 / 976
= 639
Step2:
LCM(1, 338) = 338
GCD(1, 338) = ( 1 x 338 ) / 338
= 1 / 338
= 1
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 639, 976, 338, 457 is 1
