Given numbers are 639, 806, 519, 206
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 806) = 515034
GCD(639, 806) = ( 639 x 806 ) / 515034
= 639 / 806
= 639
Step2:
LCM(1, 519) = 519
GCD(1, 519) = ( 1 x 519 ) / 519
= 1 / 519
= 1
Step3:
LCM(1, 206) = 206
GCD(1, 206) = ( 1 x 206 ) / 206
= 1 / 206
= 1
So, Greatest Common Divisor of 639, 806, 519, 206 is 1
